LETTER FROM THE CHAIRMAN 5/31/99
- --------------------------------------------------------------------------------

Dear Shareowner,
- --------------------------------------------------------------------------------

I am pleased to introduce this semiannual report for Pioneer International
Growth Fund covering the six months ended May 31, 1999. Thank you for your
investment with Pioneer and this opportunity to speak to you briefly about the
international investing environment.

The international investing landscape continued to shift as the more established
markets of Europe slipped into economic malaise while the emerging markets of
Asia showed real promise of a recovery. For Europe, there are positive signs on
the horizon. Recent events involving mergers and acquisitions on the continent
as well as strong cost-cutting measures by companies throughout the region are
proving to the world that European companies are getting serious about market
competitiveness and shareholder value. The resurgent Asian markets such as
Singapore, Taiwan and South Korea - which reported positive economic numbers for
the first quarter of 1999 - could mean greater demand for European goods and
services. Investing in international markets - especially emerging markets -
comes with special risks and volatility, but we believe, with the proper
discipline, the international marketplace holds promise for investors in the
coming years.

Of course extracting the potential reward from overseas investments, which can
be inherently more risky, takes hard work. It requires time and experience.
Nowhere are the fundamentals of long-term investing more important than
overseas. At Pioneer, we invest from the ground up. It means talking face to
face with management - wherever they live and work - to garner concrete facts,
facts that tell us about a company's balance sheet, management's commitment to
excellence and any competitive edge the company might have. These are the key
elements that define a successful company over time and, we believe, a
successful investment as well.

I encourage you to read on and learn more about Pioneer International Growth
Fund. If you have any questions about your Fund, please contact your investment
professional, or call Pioneer at 1-800-225-6292.



Respectfully,

/s/ John F. Cogan, Jr.

   their original cost.

The Morgan Stanley Capital International (MSCI) Europe Index is a
capitalization-weighted index of the 15 European country indexes included in the
MSCI EAFE (Europe, Australasia, Far East) Index. These countries are: Austria,
Belgium, Denmark, Finland, France, Germany, Ireland, Italy, Netherlands, Norway,
Portugal, Spain, Sweden, Switzerland and the United Kingdom. Index returns are
calculated monthly, assume reinvestment of dividends and, unlike Fund returns,
do not reflect any fees, expenses or sales charges. You cannot invest directly
in the Index.

Past performance does not guarantee future results. Return and share price
fluctuate, and your shares, when redeemed, may be worth more or less than their
original cost.

PORTFOLIO MANAGEMENT DISCUSSION  5/31/99
- --------------------------------------------------------------------------------



The performance of international markets improved during the six months ended
May 31, 1999 - helped in large part by Japan, Asia and Latin America. However,
investors remain somewhat cautious, as memories of last autumn's market
correction still linger. This attitude is steering investors toward larger, more
well-established companies offshore. Following is an interview with Pavlos M.
Alexandrakis, Senior Vice-President and the Fund's portfolio manager. He
discusses the turnaround in many overseas markets and its impact on his
repositioning of the Fund's portfolio.

Q:  How did the Fund perform during the six months ended May 31?

A:  While the Fund performed well in the latter months of the period, it
    underperformed across the full period generating total returns of 2.99% for
    Class A shares, 2.47% for Class B shares and 2.50% for Class C shares, all
    at net asset value. An increased exposure to the United Kingdom and Japan
    helped performance, but the Fund's reduced weighting in emerging markets
    limited its participation in the rally. The 593 international funds tracked
    by Lipper, Inc. returned an average of 4.98% for the same period. (Lipper
    is an independent firm that measures mutual fund performance.) The Fund's
    comparative benchmark, the Morgan Stanley Capital International (MSCI) EAFE
    (Europe, Australasia, Far East) Index rose 4.01%.

Q:  Have you completed the Fund's repositioning?

A:  It's fair to say that the bulk of our repositioning effort is complete,
    although we would always expect to fine-tune the portfolio in response to
    changing market conditions. Increasing large European and Japanese holdings
    and reducing smaller company and emerging market investments lowered the
    Fund's risk profile and should help protect its net asset value in periods
    of declining markets. However, this strategy may limit upside potential. We
    believe it is constructive given recent volatility and the inherent risks
    associated with international investing, including currency fluctuations
    and political and economic uncertainties.

Q:  Can the turnaround in the Pacific Rim be considered a full recovery?

A:  Southeast Asia has been on the mend for several months now, and stock prices
    have risen dramatically. However, a full recovery will take

    some time. The region's businesses must continue to restructure and
    reduce their debt to compete effectively in the world economy. In addition,
    China's economic stability is in question. Major difficulties there could
    choke the region's fragile recovery.

    In Japan, now the second largest weighting in the Fund, Investors are
    applauding the government's efforts to reform its banking system and
    stimulate consumer demand. These new growth initiatives are having a
    positive effect on stock prices. In addition to increasing the size of
    existing holdings such as Sankyo, we bought Softbank, a local internet
    company, and Oriental Land, which operates Disney World in Japan.

    In Australia, low inflation, strong domestic demand and falling
    unemployment are contributing to rising stock prices. Fund holding News
    Corp., Rupert Murdoch's multimedia conglomerate, is producing and
    distributing some of the most successful TV and movie entertainment -
    including NYPD Blue, Titanic and the newest Star Wars episode. We also
    bought WMC, one of the world's lowest-cost producers of nickel and
    aluminum. During the two years since the onset of the emerging market
    crisis, commodity exporters have seen prices of raw materials drop
    precipitously, but we believe a strong rebound may be near. Historically,
    commodity prices have moved upward sharply into a recovery.

Q:  Why have European stocks been so lackluster?

A:  Actually, there were a few bright spots across Europe - Sweden roughly
    matched the performance of the Standard & Poor's 500 Index in local
    currency while the United Kingdom outperformed. However, when the effect of
    the euro is factored in for participating countries, the whole of Europe
    tells another story. The euro has declined almost 12% against the U.S.
    dollar since its introduction in January, although this situation is
    helping European exporters somewhat, including Fund holdings Siemens
    (Germany) and Philips Electronics (Netherlands).

    Continental Europe's growth remains sluggish. Germany's economy in
    particular suffered disproportionately as a result of the emerging markets
    crisis, but there has been good news of late. Economic output rose faster
    than expected in the first quarter of this year.


                                                                               7

- --------------------------------------------------------------------------------


    Falling interest rates, job growth and consumer confidence should become a
    driving force for further economic recovery throughout Europe next year.

Q:  Are you finding opportunities in Europe?

A:  Holdings in the United Kingdom nearly doubled to 21% of equity assets.
    These stocks are benefiting from several positive factors - falling
    interest rates in particular. The Bank of England has dropped short-term
    interest rates seven times since September, and more cuts may be in store.
    The lower rates have already brought improvements in the housing, retailing
    and service sectors.

    We've also found several promising restructuring candidates in Europe that
    we think offer tremendous value. These companies are taking steps to
    improve returns and boost global competitiveness by merging, spinning off
    unprofitable subsidiaries or reducing costs. Barclays (U.K.), Elf Aquitaine
    (France) and Hoechst (Germany) all fit this profile.

Q:  In light of Brazil's recent positive economic news, are you feeling more
    confident about Latin America?

A:  We are more comfortable with prospects around the region, especially given
    the relatively calm reception of Brazil's currency devaluation. While it's
    too soon to tell if Brazil will avert a severe recession, recent reports of
    falling inflation and gross domestic product have been more upbeat than
    analysts' and government estimates. Overall, we are cautiously optimistic
    and slightly increased positions in Brazil, Argentina and Mexico.

Q:  What's in store for the balance of 1999?

A:  If emerging markets remain strong, investors are likely to remain
    interested. However, in the aftermath of recent stellar gains, we would not
    be surprised to see profit-taking break the momentum of Southeast Asia's
    rally in the second half of 1999. In Europe, we expect to see signs of a
    full-fledged economic recovery later this year. In the meantime, the
    ability of the United States to maintain its economic growth will be a
    decisive factor in the continued improvement of international stock prices
    and your Fund's holdings.

NOTES TO FINANCIAL STATEMENTS  5/31/99
- --------------------------------------------------------------------------------


1. Organization and Significant Accounting Policies

Pioneer International Growth Fund (the Fund) is a Delaware business trust
registered under the Investment Company Act of 1940 as a diversified, open-end
management investment company. The investment objective of the Fund is to seek
long-term growth of capital.

The Fund offers three classes of shares - Class A, Class B and Class C shares.
Shares of Class A, Class B and Class C each represent an interest in the same
portfolio of investments of the Fund and have equal rights to voting,
redemptions, dividends and liquidation, except that each class of shares can
bear different transfer agent and distribution fees, and have exclusive voting
rights with respect to the distribution plans that have been adopted by Class A,
Class B and Class C shareholders, respectively.

The Fund's financial statements have been prepared in conformity with generally
accepted accounting principles that require the management of the Fund to, among
other things, make estimates and assumptions that affect the reported amounts of
assets and liabilities, the disclosure of contingent assets and liabilities at
the date of the financial statements, and the reported amounts of revenues and
expenses during the reporting periods. Actual results could differ from those
estimates. The following is a summary of significant accounting policies
consistently followed by the Fund, which are in conformity with those generally
accepted in the investment company industry:


A. Security Valuation

   Security transactions are recorded on trade date. The net asset value is
   computed once daily, on each day the New York Exchange is open, as of the
   close of regular trading on the Exchange. In computing the net asset value,
   securities are valued at the last sale price on the principal exchange where
   they are traded. Securities that have not traded on the date of valuation, or
   securities for which sale prices are not generally reported, are valued at
   the mean between the last bid and asked prices. Securities for which market
   quotations are not readily available are valued at their fair values as
   determined by, or under the direction of, the Board of Trustees. Trading in
   foreign securities is substantially completed each day at various times prior
   to the close of the New York Stock Exchange. The values of


24


<PAGE>


Pioneer International Growth Fund

- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------

   such securities used in computing the net asset value of the Fund's shares
   are determined as of such times. Dividend income is recorded on the
   ex-dividend date, except that certain dividends from foreign securities where
   the ex-dividend date may have passed are recorded as soon as the Fund is
   informed of the ex-dividend data in the exercise of reasonable diligence.
   Interest income is recorded on the accrual basis, net of unrecoverable
   foreign taxes withheld at the applicable country rates. Temporary cash
   investments are valued at amortized cost.

   Gains and losses on sales of investments are calculated on the identified
   cost method for both financial reporting and federal income tax purposes. It
   is the Fund's practice to first select for sale those securities that have
   the highest cost and also qualify for long-term capital gain or loss
   treatment for tax purposes.

   The Fund's  investments  in emerging  markets or countries  with limited or
   developing markets,  may subject the Fund to greater degree of risk than in
   a  developed  market.  Risks  associated  with  these  developing  markets,
   attributable to political, social or economic factors, may affect the price
   of the Fund's  investments and income  generated by these  investments,  as
   well as the Fund's ability to repatriate such amounts. In addition,  delays
   are common in  registering  transfers of securities in India,  and the Fund
   may be unable to sell portfolio  securities until the registration  process
   is completed.

B. Foreign Currency Translation

   The books and records of the Fund are maintained in U.S. dollars. Amounts
   denominated in foreign currencies are translated into U.S. dollars using
   current exchange rates.

   Net realized gains and losses on foreign currency transactions represent,
   among other things, the net realized gains and losses on foreign currency
   contracts, disposition of foreign currencies and the difference between the
   amount of income accrued and the U.S. dollar actually received. Further, the
   effects of changes in foreign currency exchange rates on investments are not
   segregated in the statement of operations from the effects of changes in
   market price of those securities but are included with the net realized and
   unrealized gain or loss on investments.





                                                                              25

NOTES TO FINANCIAL STATEMENTS  5/31/99                               (continued)
- --------------------------------------------------------------------------------


C. Forward Foreign Currency Contracts

   The Fund enters into forward foreign currency contracts (contracts) for the
   purchase or sale of a specific foreign currency at a fixed price on a future
   date as a hedge or cross-hedge against either specific investment
   transactions (settlement hedges) or portfolio positions (portfolio hedges).
   All contracts are marked to market daily at the applicable exchange rates,
   and any resulting unrealized gains or losses are recorded in the Fund's
   financial statements. The Fund records realized gains and losses at the time
   a portfolio hedge is offset by entry into a closing transaction or
   extinguished by delivery of the currency. Risks may arise upon entering into
   these contracts from the potential inability of counterparties to meet the
   terms of the contract and from unanticipated movements in the value of
   foreign currencies relative to the U.S. dollar (see Note 6).

D. Federal Income Taxes

   It is the Fund's policy to comply with the requirements of the Internal
   Revenue Code applicable to regulated investment companies and to distribute
   all of its taxable income and net realized capital gains, if any, to its
   shareholders. Therefore, no federal income tax provision is required.

   In addition to the requirements of the Internal Revenue Code, the Fund may
   also be required to pay local taxes on the recognition of capital gains
   and/or repatriation of foreign currencies in certain countries. During the
   six months ended May 31, 1999, the Fund paid no such taxes.

   In determining the daily net asset value, the Fund estimates the reserve for
   such taxes, if any, associated with investments in certain countries. The
   estimated reserve for capital gains is based on the net unrealized
   appreciation on certain portfolio securities, the holding period of such
   securities and the related tax rates, tax loss carryforward (if applicable)
   and other such factors. As of May 31, 1999, the Fund had a reserve of
   $238,142 related to capital gains. The estimated reserve for repatriation of
   foreign currencies is based on principal balances and/or unrealized
   appreciation of applicable securities, the holding period of such investments
   and the related tax rates and other such factors. As of May 31, 1999, the
   Fund had a reserve of $1,081,705 related to taxes on the repatriation of
   foreign currencies.

- --------------------------------------------------------------------------------


   The characterization of distributions to shareholders for financial reporting
   purposes is determined in accordance with federal income tax rules.
   Therefore, the source of the Fund's distributions may be shown in the
   accompanying financial statements as either from or in excess of net
   investment income or net realized gain on investment transactions, or from
   paid-in capital, depending on the type of book/tax differences that may
   exist.

E. Fund Shares

   The Fund records sales and repurchases of its shares on trade date. Net
   losses, if any, as a result of cancellations are absorbed by Pioneer Funds
   Distributor, Inc. (PFD), the principal underwriter for the Fund and an
   indirect subsidiary of The Pioneer Group, Inc. (PGI). PFD earned $54,722 in
   underwriting commissions on the sale of fund shares during the six months
   ended May 31, 1999.

F. Class Allocations

   Distribution fees are calculated based on the average daily net assets
   attributable to Class A, Class B and Class C shares of the Fund,
   respectively. Shareholders of each class share all expenses and fees paid to
   the transfer agent, Pioneering Services Corporation (PSC), for their
   services, which are allocated based on the number of accounts in each class
   and the ratable allocation of related out-of-pocket expense (see Note 3).
   Income, common expenses and realized and unrealized gains and losses are
   calculated at the Fund level and allocated daily to each class of shares
   based on the respective percentage of adjusted net assets at the beginning of
   the day.

   Distributions to shareholders are recorded as of the ex-dividend date.
   Distributions paid by the Fund with respect to each class of shares are
   calculated in the same manner, at the same time, and in the same amount,
   except that Class A, Class B and Class C shares can bear different transfer
   agent and distribution fees.

G. Repurchase Agreements

   With respect to repurchase agreements entered into by the Fund, the value of
   the underlying securities (collateral), including accrued interest received
   from counterparties, is required to be at least equal to or in excess of the
   value of the repurchase agreement at the time of purchase.

                                                                             27

NOTES TO FINANCIAL STATEMENTS  5/31/99                               (continued)
- --------------------------------------------------------------------------------


   The collateral for all repurchase agreements is held in safe-keeping in the
   customer-only account of the Fund's custodian, or subcustodians. The Fund's
   investment adviser, Pioneer Investment Management, Inc. (PIM), is responsible
   for determining that the value of the collateral remains at least equal to
   the repurchase price.


2. Management Agreement

PIM manages the Fund's portfolio and is a wholly owned subsidiary of PGI.
Management fees are calculated daily at the annual rate of 1.00% of the Fund's
average daily net assets up to $300 million; 0.85% of the next $200 million; and
0.75% of excess over $500 million.

In addition, under the management and administration agreements, certain other
services and costs, including accounting, regulatory reporting and insurance
premiums, are paid by the Fund. At May 31, 1999, $262,347 was payable to PIM
related to management fees, administrative and certain other expenses.


3. Transfer Agent

PSC, a wholly owned subsidiary of PGI, provides substantially all transfer agent
and shareholder services to the Fund at negotiated rates. Included in due to
affiliates is $123,304 in transfer agent fees payable to PSC at May 31, 1999.


4. Distribution Plans

The Fund adopted a Plan of Distribution for each class of shares (Class A Plan,
Class B Plan and Class C Plan) in accordance with Rule 12b-1 of the Investment
Company Act of 1940. Pursuant to the Class A Plan, the Fund pays PFD a service
fee of up to 0.25% of the Fund's average daily net assets in reimbursement of
its actual expenditures to finance activities primarily intended to result in
the sale of Class A shares. Pursuant to the Class B Plan and the Class C Plan,
the Fund pays PFD 1.00% of the average daily net assets attributable to each
class of shares. The fee consists of a 0.25% service fee and a 0.75%
distribution fee paid as compensation for personal services and/or account
maintenance services or distribution services with regard to Class B and Class C
shares. Included in due to affiliates is $93,240 in distribution fees payable to
PFD at May 31, 1999.

- --------------------------------------------------------------------------------


In addition, redemptions of each class of shares may be subject to a contingent
deferred sales charge (CDSC). A CDSC of 1.00% may be imposed on redemptions of
certain net asset value purchases of Class A shares within one year of purchase.
Class B shares that are redeemed within six years of purchase are subject to a
CDSC at declining rates beginning at 4.0%, based on the lower of cost or market
value of shares being redeemed. Redemptions of Class C shares within one year of
purchase are subject to a CDSC of 1.00%. Proceeds from the CDSCs are paid to
PFD. For the six months ended May 31, 1999, CDSCs in the amount of $142,132 were
paid to PFD.


5. Expense Offsets

The Fund has entered into certain expense offset arrangements resulting in a
reduction in the Fund's total expenses. For the six months ended May 31, 1999,
the Fund's expenses were reduced by $15,021 under such arrangements.


6. Forward Foreign Currency Contracts

At May 31, 1999, the Fund had entered into various contracts that obligate the
Fund to deliver currencies at specified future dates. At the maturity of a
contract, the Fund must make delivery of the foreign currency. Alternatively,
prior to the settlement date of a portfolio hedge, the Fund may close out such
contracts by entering into an offsetting hedge contract. Open portfolio hedges
at May 31, 1999 were as follows:

Funds), collectively participates in a $50 million committed, unsecured
revolving line of credit facility. Borrowings are used solely for temporary or
emergency purposes. The Fund may borrow up to the lesser of $50 million or the
limits set by its prospectus for borrowings. Interest on collective borrowings
of up to $25 million is payable at the Federal Funds Rate plus 3/8% on an
annualized basis, or at the Federal Funds Rate plus 1/2% if the borrowing
exceeds $25 million at any one time. The Funds pay an annual commitment fee for
this facility. The commitment fee is allocated among such Funds based on their
respective borrowing limits.

The average daily amount of borrowings outstanding during the six months ended

period were 20,536,658 resulting in an average borrowing per share of $0.06. The

RETIREMENT PLANS FROM PIONEER
- --------------------------------------------------------------------------------


Pioneer has a long history of helping people work toward their retirement goals,
offering plans suited to the individual investor and businesses of all sizes.
For more information on Pioneer retirement plans, contact your investment
professional, or call Pioneer at 1-800-622-0176.


Individual Retirement Account (IRA)
Traditional IRA
A Traditional IRA allows anyone under age 70-1/2 with earned income to
contribute up to $2,000 annually. Spouses may contribute up to $2,000 annually
into a separate IRA, for a total of $4,000 per year for a married couple.
Earnings are tax-deferred, and contributions may be tax-deductible.


Roth IRA
Contributions, up to $2,000 a year per person in earned income, are not
tax-deductible, but earnings are tax-free for qualified withdrawals. You can
contribute beyond age 70-1/2, although there are income limits for contributions
at any age.


401(k) Plan
The traditional 401(k) plan allows employees to make pre-tax contributions
through payroll deduction, up to $10,000 per year or 25% of pay, whichever is
less. Employers may contribute.


SIMPLE (Savings Incentive Match PLan for Employees) IRA Plan
Businesses with 100 or fewer eligible employees can establish the plan; it
resembles a traditional 401(k), but with less testing and lower administration
costs. Employees can make pre-tax contributions of up to $6,000 per year, and an
employer contribution is required.




         Most retirement plan withdrawals must meet specific conditions
                               to avoid penalties.

403(b) Plan
Also known as a Tax-Sheltered Account (TSA), a 403(b) plan is available only to
employees of public schools, not-for-profit hospitals and other tax-exempt
organizations. A 403(b) plan lets employees set aside a portion of their salary,
before taxes, through payroll deduction.


Simplified Employee Pension Plan (SEP)
SEPs let self-employed people and small-business owners make tax-deductible
contributions of up to 15% of their income. Generally, employers must contribute
the same percentage of pay for themselves and any eligible employees;
contributions are made directly to employees' IRAs. SEPs are easy to administer
and can be an especially good choice for firms with few or no employees.


Profit Sharing Plan
Profit sharing plans offer companies considerable flexibility, allowing them to
decide each year whether a contribution will be made and how much, up to 15% of
each participant's pay. These plans can include provisions for loans and vesting
schedules.


Age-Weighted Profit Sharing Plan
Like traditional profit sharing plans, employer contributions are flexible, but
age-weighted plans allocate contributions based on both age and salary.
Age-weighted plans are designed for employers who want to maximize their own
contributions while keeping contributions to employees affordable.


Money Purchase Pension Plan (MPP)
Money purchase plans are similar to profit-sharing plans, but allow for higher
annual contributions - up to 25% of pay. MPPs aren't as flexible as profit
sharing plans; a fixed percentage of pay must be contributed each year,
determined when the plan is established. Businesses often set up both MPPs and
profit sharing plans.




         Most retirement plan withdrawals must meet specific conditions
                               to avoid penalties.

90-Day Reinstatement Privilege (for Class A Shares)

Pioneer account - without paying a sales charge - within 90 days of your
redemption. You have the choice of investing in any Pioneer fund, as long as
you meet its minimum investment requirement.

Investomatic Plan
An easy and convenient way for you to invest on a regular basis. All you need
to do is authorize a set amount of money to be moved out of your bank account
into the Pioneer fund of your choice. Investomatic also allows you to change
the dollar amount, frequency and investment date right over the phone. By
putting aside affordable amounts of money regularly, you can build a long-term
investment without sacrificing your current standard of living.

Payroll Investment Program (PIP)
Lets you invest in a Pioneer fund directly through your paycheck. All that's
involved is for your employer to fill out an authorization form allowing
Pioneer to deduct from participating employees' paychecks. You specify the
dollar amount you want to invest into the Pioneer fund(s) of your choice.

Automatic Exchange Program
A simple way to move money from one Pioneer fund to another over a period of
time. Just invest a lump sum in one fund, and select the other Pioneer funds you
wish to invest in. You choose the amounts and dates for Pioneer to sell shares
of your original fund and use the proceeds to buy shares of the other funds you
have chosen. Over time, your investment will be shifted out of the original
fund. (Automatic Exchange is available for originating accounts with a balance
of $5,000 or more.)


Directed Dividends
Lets you invest cash dividends from one Pioneer fund to an account in another
Pioneer fund with no sales charge or fee. Simply fill out the applicable
information on a Pioneer Account Options Form. (This program is available for
dividend payments only; capital gains distributions are not eligible at this
time.)


Direct Deposit
Lets you move money into your bank account using electronic funds transfer
(EFT). EFT moves your money faster than you would receive a check, eliminates
unnecessary paper and mail, and avoids lost checks. Simply fill out a Pioneer
Direct Deposit Form, giving your instructions.


Systematic Withdrawal Plan (SWP)
Lets you establish automatic withdrawals from your account at set intervals. You
decide the frequency and the day of the month you want. Pioneer will send the
proceeds by check to the address you designate, or electronically to your bank
account. You also can authorize Pioneer to make the redemptions payable to
someone else. (SWPs are available for accounts with a value of $10,000 or more.)
