LETTER FROM THE CHAIRMAN 11/30/98

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

I am pleased to introduce this report for Pioneer International Growth Fund,
covering the fiscal year ended November 30, 1998. On behalf of the Fund's
investment team, I thank you for your interest and this opportunity to comment
briefly on today's investing environment.

While Japan, Europe and emerging markets around the world are in various stages
of development, all are trying to build or improve their economic infrastructure
to compete in a global economy and offer international investors a compelling
reason to invest. At Pioneer, we continue to believe in the value opportunities
available not only in emerging markets and the smaller companies in Europe and
Asia, but in some of the larger "blue-chip" companies as well. We believe this
balanced, diversified approach to international investing can work for patient,
long-term investors.

I would like to take a moment to note that the end of this fiscal year marks the
end of an era. Current portfolio manager and the Fund's originator, Dr. Norman
Kurland, stepped down after almost six years at the helm of Pioneer
International Growth Fund. We wish him all the best and thank him for his years
of service. His successor, Pavlos M. Alexandrakis, assumed responsibility for
the day to day management of the Fund on January 8, 1999. He has been an
international investment manager for our institutional clients since joining
Pioneer in October 1998. We're confident that his 14 years of industry
experience will serve you well.

I encourage you to read on to learn more about your Fund. The Portfolio
Management Discussion in this report is especially important as it discusses
changes to your Fund's portfolio over the past year and likely changes for 1999.
Please contact your investment professional, or us at 1-800-225-6292, if you
have questions about Pioneer International Growth Fund.

Respectfully,


/s/John F. Cogan, Jr.


John F. Cogan, Jr.
Chairman and President

As Pioneer International Growth Fund's fiscal year came to a close, one of the
most volatile periods in international investing showed signs that it too may be
coming to an end or at least turning the corner. Following is an interview with
Pavlos M. Alexandrakis, senior vice-president and the Fund's portfolio manager.
Mr. Alexandrakis handles the day-to-day management of the Fund.

Q:  How did volatility affect the Fund's performance over the last year?

A:  Although the Fund showed strong results in the last quarter of the fiscal
    year, its strong finish was not enough to erase the first nine months of
    losses. Interestingly, the investment strategies that hurt performance in
    the first three quarters produced its outperformance in the last. For the
    fiscal year as a whole, Class A Shares posted a total return of -9.35% at
    net asset value, while the 511 funds in Lipper's International category had
    an average return of 10.4%. The Fund's comparative index, the Morgan Stanley
    Capital International (MSCI) EAFE (Europe, Australasia, Far East) Index
    returned 16.51%. (Lipper Analytical Services, Inc. is an independent
    research firm that tracks mutual fund performance.)

Q:  What caused the Fund's underperformance?

A:  The Fund has always relied on an investment strategy that favors
    value-oriented stocks. That means we like inexpensive stocks - as long as
    the underlying companies meet our requirements for strong financial health
    and sound business fundamentals. This investment approach led us away from
    expensive European large company stocks and directed us to the extraordinary
    values in emerging markets and small company stocks in Europe. This was a
    different direction than many other funds took. It proved to be a costly
    decision, since large companies led one of the strongest bull markets in
    Europe's history. At the same time, Asia continued to suffer through one of
    its worst bear markets ever. Generally speaking, international investors
    fled small company stocks - and Asia nearly altogether - pumping money into
    large "blue-chip" stocks in Europe and the United States.

    In late August, Russia defaulted on loans, sending investors out of even the
    blue chips. To forestall widespread and lasting panic and economic collapse,
    governments around the world cut interest rates. Confidence returned,
    especially for emerging markets where hard-pressed companies used the lower
    rates to restructure debt and improve their balance sheets. Investors began
    to notice the outstanding values available in these areas. When money
    started flowing back into the neglected developing markets in October and
    November, your Fund was fully invested and well-positioned to benefit from
    the rally.

Q:  Where, specifically, did the Fund benefit from the rally?

A:  As of November 30, the Fund's portfolio was overweighted in emerging markets
    compared to the MSCI EAFE Index. Many of these investments helped in the
    last quarter. PT Matahari Putra Prima (Indonesia) which owns that nation's
    largest chain of super-malls, Pohang Iron and Steel (Korea) and Samsung
    Electronics (Korea) both did well. Despite a slow Korean economy and a tough
    global steel market, Pohang found a way to deliver relatively strong
    operating results. Samsung Electronics is one of the world's largest
    manufacturers of memory chips, or DRAMs, used in consumer electronics and
    personal computers.

    Korea itself had a good year. Working with the International Monetary Fund,
    it stabilized its currency, brought down interest rates and turned around
    its current account status. Although Korea still has problems, including
    huge debts, it is a good example of an emerging markets country that has
    worked hard to put itself back on the global investing map - helping to
    break the wall of fear around emerging markets.


                                                                               7

PORTFOLIO MANAGEMENT DISCUSSION 11/30/98                         (continued)

    In Europe, value-oriented small capitalization companies like Powerscreen
    International (U.K.), which makes equipment for recycling in
    materials-handling industries, recovered strongly after a steep decline.
    Other examples of price recovery include BTR and Siebe, two large companies
    held by the Fund; they're now merging to form a global leader in the key
    controls and automation markets.

Q:  How was the year's volatility handled?

A:  Last year illustrated the risks of investing overseas (especially in
    emerging markets) where currency fluctuations, political strife and other
    factors can affect the performance of international investments.

    Over the course of the year, to balance the portfolio and reduce volatility,
    we shed more than half of portfolio holdings in emerging markets and also
    cut down investments in small companies. By the end of November, the Fund's
    emerging markets component was about 10% of equity assets, with less than a
    quarter of the portfolio in small caps. We moved the portfolio into
    larger-capitalization stocks including DaimlerChrysler (Germany) and more
    defensive stocks, such as Scottish Power (U.K.) and the French water
    utility, Suez Lyonnaise Des Eaux. In Europe - especially Finland,
    Switzerland and Italy - the Fund continued to invest in a surging worldwide
    telecommunications industry.

Q:  What do you see ahead for international investing and the Fund in 1999?

A:  We're encouraged as Europe swings into the first phase of its unification,
    starting in January 1999. We expect the removal of trade barriers throughout
    Europe will increase competition and produce stronger more efficient
    companies and that bodes well for Europe's economic future. When we can find
    large European companies with solid business fundamentals and good prices,
    we will add them to the portfolio. This includes investing in the more
    defensive pharmaceutical and utility sectors. We will also continue to
    decrease the portfolio's overall exposure to small company stocks.

    Although the Fund won't return to the heavy allocation at the beginning of
    the year, we will continue to be active in emerging markets. We expect to
    concentrate on Asia where we see positive signs for a future recovery. Latin
    America, we think, may have some slow years ahead, and we have chosen to
    pull most investments from there for the time being. Our goal is to build a
    balanced portfolio of quality stocks we think can provide our shareowners
    with a solid return in 1999. In addition, a potential recovery in
    undervalued emerging markets and small company stocks should add some spice
    to returns.

NOTES TO FINANCIAL STATEMENTS 11/30/98

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 Stock 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 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


                                                                              27
<PAGE>

Pioneer International Growth Fund

NOTES TO FINANCIAL STATEMENTS 11/30/98                            (continued)

   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.

   At November 30, 1998, the Fund also had investments in certain securities
   with a market value of $8,316,214 which, if sold, cannot be repatriated until
   one year after sale.


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.


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


28
<PAGE>

Pioneer International Growth Fund


   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 net realized capital gains in certain
   countries. The required capital gains taxes, if any, are determined in
   accordance with local tax laws. In determining daily net asset value, the
   Fund estimates the reserve for capital gains taxes, if any, associated with
   net unrealized gains on certain portfolio securities. The estimated reserve
   for capital gains taxes, if any, is based on the holding periods of such
   securities and the related tax rates, tax loss carryforward (if applicable)
   and other such factors. During the year ended November 30, 1998, the Fund
   paid no capital gains taxes on the sale of certain foreign securities.

   At November 30, 1998, the Fund has reclassified $5,431,177 from accumulated
   net realized loss on investments and foreign currency transactions to
   distributions in excess of net investment income. The reclassification has no
   impact on the net asset value of the Fund and is designed to present the
   Fund's capital accounts on a tax basis.


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 $237,661 in
   underwriting commissions on the sale of fund shares during the year ended
   November 30, 1998.


                                                                              29

NOTES TO FINANCIAL STATEMENTS 11/30/98                            (continued)

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. The collateral for
   all repurchase agreements is held in safekeeping in the customer-only account
   of the Fund's custodian, or subcustodians. The Fund's investment adviser,
   Pioneer Investment Management, Inc. (PIM) (formerly Pioneering Management
   Corp.), 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 the 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 November 30, 1998,

30
<PAGE>

Pioneer International Growth Fund

$318,398 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 $207,090 in transfer agent fees payable to PSC at November 30,
1998.


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 $115,947 in distribution fees payable
to PFD at November 30, 1998.

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 CDSC are paid to PFD.

6. Forward Foreign Currency Contracts

At November 30, 1998, 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 November 30, 1998 were as follows:

7. Line of Credit Facility

Effective April 14, 1998, the Fund, along with certain other funds in the
Pioneer Family of Funds (the Funds), collectively participate 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. For the period ended November
30, 1998, the Fund had no borrowings under this agreement.

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)
An IRA is a tax-favored account that allows anyone under age 701/2 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
The Roth IRA lets investors contribute up to $2,000 a year. Contributions are
not tax-deductible, but earnings are tax-free for qualified withdrawals.


401(k) Plan
The traditional 401(k) plan allows employees to make pre-tax contributions
through payroll deduction, up to $9,500 per year or 25% of pay, whichever is
less. Employers may contribute.


SIMPLE (Savings Incentive Match Plan for Employees) 
401(k) or IRA Plan
Businesses with 100 or fewer eligible employees can establish either plan; both
resemble the 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.

                                                                              37
