Long-term follow-up after adjuvant chemotherapy in completely resected early stage ovarian carcinoma.

OBJECTIVE: To evaluate the impact of standardized staging, surgery and adjuvant chemotherapy on survival of patients with completely resected early ovarian carcinoma. STUDY DESIGN: We performed a multicentric retrospective analysis of 283 patients with early stage ovarian carcinoma consecutively treated between 1977 and 1993. Borderline tumours were excluded. A comprehensive staging was performed during initial laparotomy. Patients were treated by standardized surgical resection and all excepted stage IA received a 6-course adjuvant chemotherapy. RESULTS: Eighty patients were excluded because of incorrect substaging, inadequate surgery and adjuvant therapy. The analysis was performed on 203 patients with completely resected early stage ovarian cancer (139, stage I; 64, stage II). Relapse-free survival and overall survival rates for stage I were 66 and 69%, respectively. Relapse-free survival and overall survival rates for stage II were 57 and 61% respectively. Median time of relapse was 18 months (range, 1-107 months). Sites of relapse were peritoneum (45%), retroperitoneal lymph nodes (37%) and distant metastases (18%). Relapses occurring within 18 months had a median survival after relapse of 9 months while later relapses had a median survival of 22 months (P = 0.005). There was no significant difference in relapse-free and overall survival according to the age, performance status and pathology. Cisplatin-based chemotherapy improved the 10-year overall survival of patients with stage IIB and IIC as compared to chemotherapy without cisplatin (oral melphalan. CMF regimen); 91 vs. 33% (P = 0.012) and 75 vs. 42% (P = 0.05), respectively. Cisplatin-based regimens did not improve survival in stage IA, IB and IIA. CONCLUSIONS: Early ovarian cancers have a good prognosis after comprehensive staging, complete surgery and adjuvant chemotherapy. Cisplatin-based regimens compared to melphalan and CMF showed a significant increase of survival in stage IIB and IIC. Prognosis of relapse depends on the relapse-free interval duration.

Survival after second-look laparotomy in advanced ovarian epithelial cancer. Study of 86 patients.

Second-look laparotomy (SLL) was performed after chemotherapy in 86 patients with advanced epithelial ovarian cancer. Seventy-one patients received cisplatin-based regimens. Median follow-up was 66 months. Negative SLL was found in 32 patients who had a 5-year survival rate of 48.3% after SLO. Microscopic residual disease was present in seven patients whose 5-year survival rate was 35.7%. Maximum residual tumor of 2 cm or less was found in 13 patients with a 5-year survival rate of 30%. Residual tumor larger than 2 cm after secondary cytoreduction was present in 20 patients; their 3-year survival rate was 19.7%. Fourteen patients with bulky residual disease who did not have cytoreduction were all dead within 17 months. Patients with initial residual tumor at first laparotomy less than 2 cm had a nearly significant advantage in survival rate over patients with residual disease greater than 2 cm and stage IV (P = 0.07). Non-responders to initial chemotherapy had a survival rate similar to that of partial responders. These findings justify discontinuation of conventional systemic chemotherapy for patients showing residual disease after SLL and secondary tumor removal in case of residual tumor at SLL. Therapeutic trials are needed in advanced ovarian cancer testing initial aggressive surgery or early debulking to avoid bulky residual disease, and consolidation therapy in patients who achieved complete pathological response or minimal residual disease.

[Prognosis in ovarian cancer as a function of the results of the second-look laparatomy].

Second-look laparotomy (SLL) was performed after chemotherapy in 106 patients with epithelial ovarian cancer. Thirteen were stage I and II and 93 stage III and IV. Seventy-eight patients received cisplatin-based regimens. Median follow-up was 60 months. Negative SLL was found in 32 patients who had a 5-year survival rate of 43.4% after SLO. Microscopy residual disease was present in 9 patients whose 5-year survival rate was 25%. Maximum residual tumor of 2 cm or less was found in 13 patients with 5-year survival rate of 30%. Residual tumor larger than 2 cm after secondary cytoreduction was present in 21 patients, their 3-year survival rate was 18.3%. Eighteen patients with bulky residual disease who did not have cytoreduction were all dead within 17 months. Patients with initial residual tumor at first laparotomy less than 2 cm had a near significant advantage in survival rate over patients with residual disease greater than 2 cm and stage IV (p = 0.07). Non-responders to initial chemotherapy had a survival rate similar to that of partial-responders. These findings justify discontinuation of conventional systemic chemotherapy for patients showing residual disease after SLL and secondary tumor removal in case of residual tumor at SLL. Therapeutic trials are needed in advanced ovarian cancer testing initial aggressive surgery or early debulking to avoid bulky residual disease and consolidation therapy in patients who achieved complete pathological response or minimal residual intraperitoneal disease.

Erythrocyte mean corpuscular volume during cytotoxic therapy is a predictive parameter of secondary leukemia in Hodgkin's disease.

Mean corpuscular volume (MCV) evolution during cytotoxic therapy was studied in 32 patients with Hodgkin's disease (HD) who developed therapy-related acute nonlymphocytic leukemia (t-ANLL) and in 64 HD controls matched for age, therapy duration, and MOPP (mechlorethamine, vincristine, procarbazine, and prednisone) administration. Maximum MCV during therapy reached 108.3 +/- 8.2 fl in t-ANLL patients and 103.4 +/- 9.1 fl in the controls (P = 0.001). Maximum MCV increase was 26.7 +/- 8.3 fl in t-ANLL patients and 16.6 +/- 8.3 fl in the controls (P = 10(-9). The greatest 3-month increase observed during therapy was 14.8 +/- 6 fl in the t-ANLL patients and 10.1 +/- 4.8 fl in the controls (P = 0.0001). During initial MOPP therapy, the greatest 3-month increase reached 14.1 +/- 5.3 fl in t-ANLL patients and 9.8 +/- 4.5 fl in the controls (P = 0.01). The relative risk of developing t-ANLL was 9 for a MCV maximum increase over 24 fl during therapy, which was observed in 71% of the patients with t-ANLL and in only 22% of the controls. For the greatest 3-month MCV increase over 15 fl observed in 57% of the t-ANLL patients and in 17% of the controls, the relative risk reached 15. This suggests that there is at least one factor, independent from therapy, which predisposes to t-ANLL. MCV evolution during therapy appears useful in determining which HD patients have a high risk of developing t-ANLL.

Preleukemic changes in cases of nonlymphocytic leukemia secondary to cytotoxic therapy. Analysis of 105 cases.

Peripheral blood changes preceding therapy-related leukemia were studied in 105 patients who had received cytotoxic therapy, 53 for Hodgkin's disease and 52 for other cancers. Preleukemic anomalies were observed in 74.3% of the cases, appearing after a mean interval of 68.7 months after diagnosis of the initial cancer. This interval was only 57.5 months in patients aged 50 years or older and only 42.3 months in patients with Hodgkin's disease having received cytotoxic therapy for 6 months or less. The first changes most frequently observed were pancytopenia (24.8%) and isolated erythrocyte abnormalities such as anemia or macrocytosis (18.1%). Involvement of two cell lines, isolated thrombocytopenia or leukopenia, circulating immature cells, monocytosis, leukocytosis, or thrombocytosis were also observed. Therapy-related myelodysplastic syndrome was recognized in 19 patients and myelofibrosis in 3. Median duration of the preleukemic phase was 6 months; 9 months in cases of isolated erythrocyte involvement and 5 months in the other cases. Myelomonocytic or monoblastic leukemia appeared less frequently when the first sign involved erythrocytes only. Hematological surveillance thus appears necessary in all patients having received cytotoxic therapy. Bone marrow study with cytogenetic examination should be performed in cases of persistent peripheral blood abnormalities.

Acute leukemia after treatment for ovarian cancer. Report of four cases and review of the literature.

Four cases of acute nonlymphocytic leukemia (ANLL) following ovarian cancer are reported. All patients received alkylating agents and had a preleukemic phase. Seventy-nine additional cases of ANLL following therapy found in the literature are also reviewed. All but 2 patients received alkylating or alkylating-related agents alone or in combination. Mean duration of chemotherapy was 31.4 +/- 19.4 months. Eighty-eight percent of the patients presented with preleukemia with a mean duration of 10 +/- 10 months. Mean interval between cancer and ANLL was 57.3 +/- 26 months. Cytogenetic abnormalities were found in 71% among patients who had a karyotype. Long-term alkylating agent therapy seems to have a significant role in the development of ANLL and should be avoided in ovarian cancer.

[Chemotherapy in 143 advanced epithelial cancers of the ovary. Experience at the Hôtel-Dieu of Quebec and Hôpital Saint-Antoine (Paris)].

Results of initial chemotherapy in 143 patients with advanced epithelial ovarian cancer are presented. Twenty-five patients were treated with alkylating agents, their median survival was 13 months and 15% were alive at 4 years. Nineteen received Cyclophosphamide-Methotrexate-5 Fluorouracil with or without Hexamethylmelamine, median survival was 22 months and 4 years survival was 20%. Forty-eight were treated with Adriamycin and Cisplatinum, their objective response rate proven by second-look laparotomy was 54.4% (26.1% complete response), median survival was 23 months and 35% were alive at 4 years. Thirty-one received Hexamethylmelamine, 5 Fluorouracil, Adriamycin and Cisplatinum with a median survival of 18 months and 4 years survival of 15%. Twenty had various other chemotherapy regimens, their median survival was only 8 months. Recent advances in the therapy of ovarian carcinoma are also discussed.

Erythrocyte mean corpuscular volume during cytotoxic therapy and the risk of secondary leukemia.

Erythrocyte mean corpuscular volume (MCV) evolution during cytotoxic therapy of Hodgkin's disease, lymphoma, multiple myeloma, ovarian cancer, and breast cancer was studied. The fastest and the highest MCV increases were observed in the diseases and with the therapies the most frequently involved in secondary leukemia: Hodgkin's disease treated with MOPP (mechlorethamine, vincristine, procarbazine, prednisone), and multiple myeloma and ovarian cancer treated with melphalan. On the contrary, with cytotoxic regimens not linked to a high frequency of secondary leukemia such as CMF (cyclophosphamide, methotrexate, 5-fluorouracil) used in ovarian or breast cancer, MCV increase was moderate. As the MCV increase reflects the bone marrow reaction to cytotoxic therapy, an unusually high increase could indicate bone marrow damages which could lead to secondary leukemia.

Adriamycin and cis-platinum in advanced ovarian cancer.

Forty-eight patients with stage III and IV ovarian epithelial carcinoma were treated with single doses of adriamycin (ADM) 50 mg/m2 and cis-platinum (DDP) 50 mg/m2 every month for nine courses. The pathologically proven response rate was 52.2%, with 22.7% complete response and 29.5% partial response. Median survival was 22 months for all patients, 25 months in stage III and 15 months in stage IV. This study confirms that ADM-DDP is a valuable drug regimen in advanced ovarian carcinoma but further progress is needed to improve the cure rate, which remains low.

[Changes in the mean corpuscular volume during the cytotoxic treatment of cancer and risk of secondary leukemia. Preliminary results].

Changes in mean corpuscular volume (MCV) were studied in cancer patients. Vitamin B12 or erythrocyte folate deficiencies were observed in only 9% of macrocytic patients (MCV greater than or equal to 100 fl). Bone marrow study in seven macrocytic patients with normal hemograms and normal levels of vitamin B12 and folic acid, on per os daily cyclophosphamide single agent therapy, showed myelodysplastic features. The highest MCV and MCV increases during therapy among 203 patients were observed in those cancers and cytotoxic therapies most commonly followed by secondary leukemia: Hodgkin's disease treated with MOPP and radiotherapy, and multiple myeloma and ovarian cancer treated with Melphalan. 21 patients who developed secondary leukemia had a higher MCV and a greater MCV increment than the control patients. Differences were significant in Hodgkin's disease. This preliminary report strongly supports monitoring MCV changes during cytotoxic therapy to attempt identification of patients at high risk of secondary leukemia.

Study of erythrocyte mean corpuscular volume during cytotoxic therapy as a predictive parameter of the risk of secondary leukemia in Hodgkin's disease.

Erythrocyte mean corpuscular volume (MCV) evolution was studied during cytotoxic therapy in 12 patients with Hodgkin's disease who developed secondary acute leukemia and in 83 patients with Hodgkin's disease without secondary leukemia as control group. Significant differences were observed in the maximum MCV and in the MCV maximum increase during therapy between the two groups of patients. These differences remained significant between the patients treated with chemotherapy alone and those treated with chemotherapy and radiotherapy. MCV maximum increase greater than 23.9 fl was observed in all patients with secondary leukemia and in only 20% of those without secondary leukemia; it was reached 46.3 months before the first sign of preleukemia. Its value in predicting the leukemic risk in Hodgkin's disease is discussed.
