In a 9-year period we treated 11 patients with an epithelioid sarcoma. Most patients were young adults. The tumour affected mainly the distal upper extremity (hand and fingers: four patients; wrist and forearm: three patients); one patient had an epithelioid sarcoma of the knee. Trunk localizations were seen in two patients and one patient presented with a vulva localization. Treatment consisted of surgery, regional isolation perfusion with doxorubicin (Adriamycin) or melphalan, radiation therapy, systemic chemotherapy or a combination of these modalities. Radical surgery in eight patients resulted in only two local recurrences. Locoregional metastases occurred in five patients. In five patients a therapeutic lymph node dissection was performed, in all instances followed by extensive recurrent disease. Distant metastases were seen in seven patients and mainly affected the skeleton (6x) and the lungs (4x); in the majority of cases these metastases occurred within a year after excision of the primary. Remissions following regional or systemic chemotherapy were not observed. At the time of analysis seven patients had died as a result of their epithelioid sarcoma; two patients were still alive with tumour 18 and 27 months after diagnosis. Only two patients remained tumour free for 17 and 65 months respectively following radical surgery, postoperative radiation therapy and (in one case) adjuvant chemotherapy. It is concluded that epithelioid sarcoma is a rare but exceedingly aggressive tumour. Since early diagnosis can only be auspicious, familiarity with the clinical features is of great importance.

Fourteen patients with bone and soft tissue sarcoma were treated with post-operative intra-arterial chemotherapy. Three drugs (Adriamycin, vincristine, carboquone or THP-adriamycin, cisplatin, vindesine) or two drugs (cisplatin, vindesine) were used post-operatively for patients with local recurrence, patients with poor response of pre-operative intra-arterial chemotherapy or patients with intra-lesional or marginal surgical margin. Of the 14 patients treated with post-operative intra-arterial chemotherapy, 8 (57.1%) were continuously disease-free (7.1%) were disease-free after treatment of lung metastasis, 2 (14.3%) had a local recurrence and/or multiple distant metastasis, and 3 (21.4%) died with multiple distant metastases. The rate of local recurrence was 14.3%. The Kaplar-Meier disease free survival curves showed 59.6%). Evaluation of limb function were excellent or good in 9 (69.2%) of 13 patients treated with limb-saving procedures.

A series of 71 patients with muscle invasive bladder cancer received a median of 3 cycles (range 1-6) of methotrexate, vinblastine, Adriamycin and cisplatin (M-VAC). Efficacy assessed by transurethral resection alone showed that 48% of patients were TO, 13% Tis and 54% had normalisation of initially positive urinary cytology after treatment. However, when considering transurethral resection of the bladder (TURB), cytology and non-invasive procedures (CT scan and/or ultrasound), only 21% had a clinical complete remission (cCR); 48 patients (68%) had pathological evaluation and 13 (27%) were PO after treatment. Non-responding patients had a poor prognosis: 14/30 (47%) developed metastatic disease and 13 died. In assessing the primary lesions, clinical understaging was significant. Of 15 patients who were TO cystoscopically prior to surgery, 6 (40%) had residual disease in the pathological specimen, including 4 with muscle infiltration; 23 patients (32%) remained clinically staged, only 8 of whom remain disease-free. With a median follow-up of 24 months (range 2-42+), 41 patients are alive and disease-free, including 20 with a functional bladder. The large staging error raises questions concerning studies using clinical rather than pathological endpoints as the sole criteria of efficacy.

Since 1978, six boys with prostatic rhabdomyosarcoma have been treated at our institution. Three had localized disease and were managed by initial biopsy, vincristine, actinomycin-D, and cyclophosphamide (VAC) chemotherapy, and bladder-sparing surgery with or without irradiation. Further combination chemotherapy ("pulse" VAC, Adriamycin, VP-16, cisplatin, and ifosfamide) was continued for 20 to 22 months following the induction course. Two boys had microscopic residual disease undetected by frozen section and unresponsive to radiotherapy. Subsequent total cystectomy 4 and 7 months later resulted in eradication of disease. In one patient, preservation of the bladder was achieved at the age of 3 months for 8 years. Artificial sphincter inserted to cure his urinary incontinence failed because of ischemia secondary to cuff compression and scar tissue. He is alive today with a modified Koch pouch urinary diversion. Of the 50% who had metastatic disease at presentation, two were dead within 12 months despite aggressive chemotherapy and irradiation. The third is currently on treatment. Although chemotherapy has markedly improved the prognosis, surgery is still necessary in most cases for cure. Bladder salvage is a desirable goal; however, residual microscopic disease, difficulty with frozen-section disease detection, and poor tissue vascularization for subsequent sphincter replacement remain significant obstacles.

A case of recurrent breast cancer with metastases to the lung and bone responding well to cisplatin and vindesine in a 45-year-old woman was reported. She had a radical mastectomy for the right breast cancer (pT2N0M0) at 28 years old. She was well until March 1985, when right iliac bone pain appeared. Osteolytic changes were noted on her pelvic roentgenogram. A biopsy obtained from the right iliac bone revealed metastatic adenocarcinoma. She was admitted to our hospital in December 1985 because of chest pain and swelling of the left axillary lymph nodes. Lymph nodes also showed metastatic adenocarcinoma with positive estrogen receptor. Her chest roentgenogram demonstrated a coin lesion in the left hilum and also left pleural effusion. Cytology of the effusion revealed adenocarcinoma. She was first treated with Adriamycin, 5-FU and Cyclophosphamide, but no significant response was noted. But, after two courses of chemotherapy containing cisplatin (80 mg/m2) and vindesine (3 mg/m2), the coin lesion of the lung and pleural effusion disappeared. The osteolytic bone change of the pelvic bone also improved. The serum CEA level decreased from 34.2 ng/ml to 4.2 ng/ml. These results suggest that cisplatin and vindesine were effective for lung and bone cancers metastatic from adenocarcinoma of the breast.

There is increasing evidence that selected patients with small-cell carcinoma of the lung (SCCL) may benefit from surgical resection. Since 1983, sixteen patients (aged 40-72 years) with limited SCCL underwent surgical resection before any other treatment. Criteria for patient selection were the following: 1) no pre-operative histological diagnosis or 2) pre-operative diagnosis of T1 or T2 SCCL, without evidence of both distant and mediastinal node metastases. All patients had potentially, curative resection (lobectomy: 11 cases; pneumonectomy: 5 cases). Postoperatively patients were classified as stage I in 7 cases, as stage II in 3 cases and as stage III in 6 cases. All subjects but one subsequently received adjuvant chemotherapy (Cisplatin; Adriamycin; VP-16). Prophylactic cranial irradiation was not given. Median survival time was 15.2 months for the whole group of patients, 19.6 months for stage I patients, 16 months for stage II patients and 9.7 months for stage III patients. The 2-year survival rate was 32% for all cases, 63% for stage I cases and 0% for stage II and stage III cases. Three stage I patients are alive and disease-free, 24, 26 and 31 months after resection, respectively. The brain was the most common site of initial relapse in stage I cases. These results suggest that surgery might favor intrathoracic disease control exclusively in stage I and stage II patients. Resection seems to be contraindicated in N2 tumors. If treatment policy is to achieve total disease control, prophylactic cranial irradiation should be recommended, notably in patients with stage I SCCL.(ABSTRACT TRUNCATED AT 250 WORDS)

The patterns of disease extent, response to treatment, and survival rates were examined in 129 children registered as metastatic (Group IV) soft-tissue sarcoma patients on the Intergroup Rhabdomyosarcoma Study (IRS)-I protocol from November 1972 through October 1978. The patients' ages at diagnosis ranged from 3 months to 21 years (median, 10.5 years); 72 were male patients and 57 were female patients (male-to-female ratio, 1.3:1). The tumor arose in an extremity in 34 patients, the head and neck (exclusive of the orbit) in 27, the genitourinary tract in 25, the retroperitoneum or pelvis in 14, the trunk in 12, the intrathoracic region in nine, the hepatobiliary system in four, the perineum in two, and the orbit in two patients. The histologic types of soft-tissue sarcoma confirmed by the pathology review committee were embryonal rhabdomyosarcoma in 68 patients, alveolar rhabdomyosarcoma in 41, undifferentiated sarcoma in 14, embryonal-botryoid in two, pleomorphic in one patient, and other sarcoma in three patients. Of 105 patients who were confirmed in Group IV and had complete information concerning sites of metastatic deposits, 53 patients presented with metastases restricted to only one anatomic region or tissue; the other 52 had diffuse metastases. The most common sites of distant tumor deposits were the lungs, bone marrow, and other soft tissues. After treatment with vincristine, dactinomycin, and cyclophosphamide with or without Adriamycin (Adria Laboratories, Inc., Columbus, OH) and radiation therapy, 65 (50%) of the 129 eligible patients achieved complete disappearance of all detectable tumor. The likelihood of achieving and maintaining a complete response for 2 years was highest among patients whose tumors originated in the genitourinary tract, retroperitoneum-pelvis, or the hepatobiliary or perineum regions. Thirteen of these 45 children (29%) are alive and disease-free at a minimum of 2 years after initiation of treatment. Only 10 of the other 84 (8%) are surviving disease-free at 2 years (P = 0.02). The presence of restricted rather than diffuse metastases at diagnosis (P = 0.02) was the only other characteristic significantly related to long-term complete remissions. One hundred and two patients (79%) died at a median of 47 weeks after diagnosis, 92 from sarcoma and ten from other causes.(ABSTRACT TRUNCATED AT 400 WORDS)

Adriamycin (ADR)-resistant sublines of B16-BL6 mouse melanoma selected by exposure to increasing concentrations of ADR were characterized in vitro for growth properties and in vivo for tumorigenicity and pulmonary metastases. The progressively resistant sublines adapted to grow in the presence of 0.025, 0.05, 0.1, and 0.25 microgram/ml ADR in monolayer culture were found to be 5-, 10-, 20-, and 40-fold ADR-resistant, respectively, compared to the parental sensitive cells, using a soft-agar colony assay and continuous ADR treatment for 7 days. The doubling time in monolayer culture of the parent sensitive and progressively ADR-resistant sublines of B16-BL6 melanoma cells was approximately 16-18 h. Although the colony-forming efficiency in soft agar of parental sensitive cells was only 0.5-4%, the 5-, 10-, 20-, and 40-fold ADR-resistant sublines had colony-forming efficiencies of 15, 20, 30, and 77%, respectively. Tumorigenicity in C57BL/6 mice of progressively ADR-resistant sublines was similar to parental sensitive cells following s.c. and i.p. implantation of 10(5)-10(6) tumor cells. Experimental pulmonary metastases were significantly lower in ADR-resistant sublines with progressive resistance. Additionally, unlike the parental sensitive and 5-fold ADR-resistant B16-BL6 cells, the 10-, 20-, and 40-fold ADR-resistant sublines were spontaneously nonmetastatic. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis and immunochemical detection of P-glycoprotein revealed the presence of a Mr 170,000 plasma membrane glycoprotein in the 40-fold ADR-resistant subline and its counterpart maintained for 1 year in ADR-free medium. Results from this study suggest that progressively ADR-resistant B16-BL6 mouse melanoma cells selected in vitro demonstrate a marked increase in colony formation in soft agar and a decrease in the ability to produce pulmonary metastases, without alterations in tumorigenicity.

The purpose of this trial was to investigate the impact of systemic combination chemotherapy on survival and recurrence patterns in incompletely resected non-small-cell lung cancer. Incomplete resection was defined as presence of residual tumor in the resection margin or by presence of metastasis in the highest paratracheal lymph node sampled during protocol-directed surgical staging of the mediastinum. One hundred seventy-two patients were randomized to receive either postoperative radiotherapy (RT) alone or postoperative RT plus chemotherapy with CAP (Cytoxan [cyclophosphamide; Bristol Myers, Evansville, IN], Adriamycin [doxorubicin; Adria Laboratories, Columbus, OH], and Platinol [cisplatin; Bristol Myers]) for 6 months. One hundred sixty-four patients were eligible for analysis at a mean time since randomization of 3.7 years. The chemotherapy arm showed significantly longer recurrence-free survival (two-sided Mantel-Haenszel log rank test, P = .004). This difference holds true for nonsquamous patients (P = .01), and approaches significance for squamous patients as well (P = .08). There was a 14% difference in survival rate favoring the chemotherapy arm 1 year after randomization. Analysis of sites of recurrence showed a significant decrease in distant metastases in the chemotherapy arm. Median survival for the entire group was approximately 17 months, and 35% are alive 2 years after resection. Toxicity of treatment consisted of esophagitis (mild-moderate by Eastern Cooperative Oncology Group [ECOG] criteria) and predictable hematologic, gastrointestinal (GI), and skin toxicity expected from CAP.

The results of 144 previously untreated cases of primary Ewing's sarcoma of bone are reported with a minimum follow-up of 5 years. This series was treated between 1972 and 1982 at Istituto Ortopedico Rizzoli with a combined therapy. The local control of the disease consisted of amputation (ten cases), resection followed by radiation therapy (35-45 Gy) (48 cases) and radiation therapy alone (40-60 Gy) (86 cases). Adjuvant chemotherapy, rigorously standardized, was performed according two different protocols: the first (85 cases treated in the period 1972-1978) consisted of vincristine (VCR) Adriamycin (doxorubicin) (ADM), and cyclophosphamide (EDX); the second (59 cases treated in the period 1979-1982) of VCR, ADM, EDX and dactinomycin (DACT). At a follow-up of 5 to 16 years (median, 9), 59 patients (41%) are continuously disease-free (CDF), 81 (56%) developed metastatic disease and/or local recurrence, and four (3%) had a second malignancy. Three factors seem to be correlated to prognosis: the site of the initial lesion (only 23% of the pelvic lesions are represented in the CDF group versus 46% of the other locations); the chemotherapy protocol (32% of the cases in the first protocol are CDF versus 54% in the second); the type of local treatment (60% of the patients treated with amputation or resection plus radiotherapy versus 28% of those treated with radiation therapy alone are CDF). A local recurrence was observed in 24% of the patients (8% in the group locally treated with surgery or surgery plus radiation therapy versus 36% in the group treated with radiation therapy alone). These data suggest that even though adjuvant chemotherapy can improve the long-term results in localized Ewing's sarcoma patients, this disease still represents, in a high percentage of cases, a lethal process whose final prognosis widely depends on the local control of the lesion. Due to the questionable effect of the radiation therapy alone in controlling the primary lesion and its important side effects, the role of surgery in treating Ewing's sarcoma of bone should be extended.
