Pioneer Equity-Income Fund

LETTER FROM THE CHAIRMAN 4/30/98

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

I am pleased to introduce this semiannual report for Pioneer Equity-Income
Fund, covering the six months ended April 30, 1998. On behalf of your
investment team, I thank you for your interest and this opportunity to comment
on today's investing environment.

The United States' economic news continued to be positive, propelling our
domestic stock market to yet another series of record highs. Large-
capitalization stocks were the big winners, with the Dow Jones Industrial
Average returning over 22% as concerns about the Asian financial crisis drew
investors toward the safety of U.S. "blue chip" companies like those in your
Fund.

We believe that using a solid value approach to choosing stocks - purchasing
them at reasonable prices and holding them until we think they reach full value
- - will help provide the best opportunity for positive long-term results. While
it is impossible to predict the direction of the markets with any degree of
certainty, the fact remains that large company stocks' record-breaking pace has
pushed that group's average price-to-earnings ratio to an all-time high. The
rest of the market, on the other hand, is trading at lower levels. It would not
be surprising to see new trends emerge as investors search for more reasonable
valuations. Since markets tend to run in cycles, we encourage you to speak with
your investment professional about managing your risk by spreading your
investments among different types of funds, including those that invest
overseas or globally. Investors who maintain a diversified portfolio and a
long-term perspective have the potential to weather any short-term risks the
market may pose.

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


Respectfully,

/s/ John F. Cogan, Jr.,

John F. Cogan, Jr.,
Chairman and President

Pioneer Equity-Income Fund

PORTFOLIO MANAGEMENT DISCUSSION 4/30/98

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


We are pleased to report Pioneer Equity-Income Fund's continued success as we
hit the midpoint of its ninth fiscal year. While the stock market in the United
States has not gone up in a straight line in recent months, it has gone up, and
so has the Fund's share price.

For the six months ended April 30, 1998, the Fund delivered total returns of
18.46% for Class A Shares, 18.03% for Class B Shares and 18.00% for Class C
Shares - all at net asset value. These returns were ahead of the average
equity-income fund's return of 16.30%. (Lipper Analytical Services, Inc., an
independent mutual fund research firm, tracked 214 funds for the six months.)
Looking at the past 12 months, the Fund's returns earned it a place among the
top 16% of similar funds. (Of 197 funds, Class A Shares ranked 23, Class B, 30
and Class C, 31.)*


Dividends Are Still Important, although Not Very Popular

In the three months ended April 30, 1998, however, the Fund's performance lost
some of its momentum, and its portfolio of dividend-paying stocks lagged the
broader market. In general, the strength in the stock market has been
concentrated in "growth" names, and dividends have appeared to be of scant
interest to investors. We find that dividends can provide a useful buffer
during rough periods for stocks, and we always view a lack of emphasis on them
by investors as a sign of diminished caution.

Going back through American financial history, one learns that dividends were
frequently much more highly prized than they are today. In the 1800s, for
instance, when equity prices were not always so easy to determine and
transactions were sometimes difficult to undertake, the cash that companies
returned to stockholders in the form of dividends was regarded as the surest
kind of return. In this century, too, over some long stretches when share
prices have been relatively flat or directionless -

for example between the late 1920s and the early 1940s and between the late
1960s and early 1980s - investors have regarded dividends favorably. The
dividend yield on the Standard & Poor's 500 Index today is at an all-time low
of 1.41%; when your Fund was introduced in 1990, it was 3.28%. We do not know
where yields will go from here, but we intend to continue our emphasis on
strong dividend-payers. It is part of our discipline not to abandon caution.


The Trend toward Consolidation

Everyone who follows the stock market will certainly have taken note of the
large number of mergers and acquisitions. Companies in the United States and
Europe have been bitten by the consolidation bug. Consultants, investment
bankers and economic commentators alike have counseled companies to "bulk up"
in their basic business or combine with companies having similar kinds of
products that might then be "cross sold." To date, this trend has translated
into big gains for your Fund.

The financial services sector has seen an especially large number of such
mergers, but many other industries have also been affected - automobiles,
telecommunications, electric utilities, entertainment, transportation, oil and
gas. Your Fund has significant investments in most of these industries; a
number of holdings are, in fact, merged entities. Bell Atlantic, for example,
combines the former Bell Atlantic and Nynex, and SBC Communications joins the
former Southwestern Bell with Pacific Telesis. The portfolio received shares of
Kinder Morgan Energy Partners when it acquired Santa Fe Pacific Pipeline
Partners. Most recently, First Union absorbed CoreStates Financial in exchange
for stock. Portfolio companies Chrysler, H.F. Ahmanson, Mercantile Stores,
Ameritech and DQE have all received merger proposals. In fact, offers for
Ameritech and DQE have come from other companies in the portfolio (SBC
Communications and Allegheny Energy, respectively).

Years down the road mergers sometimes unwind, often helping boost stock prices
when investors perceive that the change will increase profitability. E.I.
DuPont de Nemours has just announced that it will begin the process of
"spinning off" its Conoco oil-and-gas subsidiary. Pepsico has already done that
with its restaurant operations, and Ford has distributed shares of Associates
First Financial. Little is "permanent" in the business world; change is usually
the norm. The magnitude and intensity of present-day corporate transactions are
remarkable, however, by any standards. For us as investment analysts, the
challenge is to look at each transaction closely and



                                                                               7

decide whether it creates the potential for additional value in our portfolio.
The market pitches opportunities at us on almost a daily basis, it seems, and
we have to choose, and fairly quickly, which ones to swing at.


The Portfolio at Midyear

Recent portfolio activity included two initial purchases and two liquidations.
Mellon Bank is a strong presence in "fee-based" financial services including
mutual funds, pension funds and shareholder services, as well as a good
operator in commercial and retail banking. Its returns on equity are high.
Johnson & Johnson is one of the oldest and most diversified pharmaceutical,
hospital-supply and consumer-healthcare products companies. Known universally
for its baby powders and Band-Aids, Johnson & Johnson has also paid dividends
regularly for many decades. In the case of the positions sold, Borden Chemicals
& Plastics and Peoples Energy, we could no longer feel confident in their
prospects relative to alternative investments. On a sector basis, we made few
adjustments over the period. The portfolio remains well diversified, and our
emphasis on telecommunications is still in place, having generated good results
to date.


Saddling Up and Moving Out

Knowing the future would not, we think, be an unalloyed benefit in investing,
popular views notwithstanding. Events are predicted everyday, but reactions to
them can be very surprising. Thus, we could know what will happen without
knowing the repercussions, and investment opportunities and difficulties often
lie in the repercussions. We always take our cues from the companies
themselves. We look at what they are doing with their capital-spending and
research-and-development dollars, and we are always looking for evidence of
change, tangible signs of new development and real commitments to futuristic
concepts. We prefer to invest in companies that are themselves investing. This
is our basic task, and this is how we believe we can help you meet your
long-term goals.

We are grateful for your continued support. Please get in touch at any time
with questions or comments.


Respectfully,

Pioneer Equity-Income Fund

NOTES TO FINANCIAL STATEMENTS 4/30/98


1. Organization and Significant Accounting Policies

Pioneer Equity-Income Fund (the Fund), one of three funds that composes Pioneer
Growth Trust, is a Massachusetts business trust registered under the Investment
Company Act of 1940 as a diversified, open-end management investment company.
The investment objectives of the Fund are current income and 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. Each day, 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. Dividend
  income is recorded on the ex-dividend date and interest income is recorded
  on the accrual basis. 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



22
<PAGE>

Pioneer Equity-Income Fund
 


  that have the highest cost and also qualify for long-term capital gain or
  loss treatment for tax purposes.

  Settlements from litigation and class action suits are recognized when the
  Fund acquires an enforceable right to such awards. Included in net realized
  gain from investments is $76,196 of class action settlements received by the
  Fund during the six months ended April 30, 1998.


B. 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.

  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.


C. 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 $213,743 in
  underwriting commissions on the sale of fund shares during the six months
  ended April 30, 1998.


D. Class Allocations

  Distribution fees are calculated based on the average daily net asset value
  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.



                                                                              23

Pioneer Equity-Income Fund

NOTES TO FINANCIAL STATEMENTS 4/30/98                              (continued)


  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.


2.  Management Agreement

Pioneering Management Corporation (PMC), the Fund's investment adviser, manages
the Fund's portfolio and is a wholly owned subsidiary of PGI. Management fees
are calculated daily at the annual rate of 0.65% of the Fund's average daily
net assets up to $300 million; 0.60% of the next $200 million; 0.50% of the
next $500 million; and 0.45% of the excess over $1 billion.

Effective May 1, 1998, management fees are calculated at the annual rate of
0.60% of the Fund's average daily net assets up to $10 billion and 0.575% of
the excess over $10 billion.

In addition, under the management agreement, certain other services and costs,
including accounting, regulatory reporting and insurance premiums, are paid by
the Fund. At April 30, 1998, $413,499 was payable to PMC related to management
fees and certain other services.


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 $109,002 in transfer agent fees payable to PSC at April 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 $342,550 in distribution fees
payable to PFD at April 30, 1998.



24
<PAGE>

Pioneer Equity-Income Fund
 


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. For the six months ended April 30, 1998, CDSCs in the
amount of $132,505 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 April 30,
1998, the Fund's expenses were reduced by $47,487 under such arrangements.


6.  Line of Credit Facility

The Fund, along with certain others 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 six months ended April 30, 1998, there
were no borrowings under this agreement.


7.  Affiliated Companies

The Fund's investments in certain companies exceed 5% of the outstanding voting
stock. Such companies are deemed affiliates of the Fund for financial reporting
purposes. The following summarizes transactions with affiliates of the Fund as
of April 30, 1998:

RESULTS OF SHAREOWNER MEETINGS                                     (continued)


The remaining proposal up for shareowner approval, Proposal 3, has been
adjourned to the shareowner meeting on June 18, 1998.

Proposal 3 - Allow the Fund to be reorganized as a separate Delaware business
trust. Currently, Pioneer Growth Trust is registered as a single Massachusetts
business trust with three funds, one of which is your Fund. As a separate
Delaware business trust, the Fund and its shareowners could benefit from a
decreased possibility of shareholder and trustee liability and various
potential operating efficiencies all described in the Proxy Statement.
