From 1970 through 1977, 92 patients with ovarian cancer received 20 Gy (2,000 rad) to the abdomen, followed by 30 Gy (3,000 rad) to the pelvis. Small-bowel obstruction developed in 7 (7.6%). The number of previous laparotomies, thin physique, and hypertension were significantly associated with complications. Two patients receiving isoniazid and 2 receiving Premarin had enteric complications. Pre-existing vascular damage may potentiate radiation damage to the small bowel.

The addition of intraperitoneal colloidal radioactive chromic phosphorus following total abdominal hysterectomy, bilateral salpingo-oophorectomy, and omentectomy in women with Stage I ovarian cancer does not cause significant morbidity. Moreover, our preliminary results suggest that this regimen appears to increase the rate of local control of disease. In 21 unselected patients, there was 1 incident of small bowel obstruction. Fourteen of these patients have been followed for at least 1 1/2 years; all are alive without evidence of disease. These facts suggest that a national prospective study to investigate the efficacy of this treatment for Stage I ovarian cancer is warranted.

Adjuvant chemoradiotherapy was administered to 26 patients with stage Ic-IV ovarian cancer after radical cytoreductive surgery. All patients received six cycles of carboplatin, epirubicin, and prednimustine and had no clinical evidence of disease after completion of chemotherapy. They received whole-abdominal radiation and radiation to the retroperitoneal lymph nodes. This protocol was discontinued for five (23%) patients because of myelosuppression, progressive disease, or withdrawal. One patient had a small bowel obstruction due to intraperitoneal adhesions. The survival of ten stage-III ovarian cancer patients, who received chemoradiotherapy and were evaluable for assessment of treatment efficacy, was retrospectively compared with the survival of 11 stage-III patients who received chemotherapy only. At 36 months, a slight advantage of the chemoradiotherapy versus the chemotherapy-only group was observed (p = 0.11). These preliminary results suggest that adjuvant chemoradiotherapy may prolong the "no evidence of disease" interval of radically operated ovarian cancer patients. Toxicity is acceptable when second-look surgery is avoided and when subsequent radiotherapy is limited to patients with no evidence of disease.

Surgery is a critical component of the multimodality approach to ovarian cancer. Surgery confirms the diagnosis and establishes the stage of disease, especially important when the tumor appears to be limited to the ovaries. In advanced disease, surgical cytoreduction improves response to chemotherapy and survival. Second-look laparotomy provides a means for assessing response to therapy, predicting prognosis, and determining the need for further therapy. Surgery can also provide palliation of intestinal obstruction.

We examined the records of 105 patients with advanced ovarian cancer who had been treated with cisplatin combination chemotherapy followed by abdominopelvic radiotherapy. The purpose was to define the morbidity of this approach, and identify those factors predictive of toxicity. Acute toxicity resulting in delay or failure to complete treatment was most commonly due to myelosuppression. Nine of 105 patients (8.6%) required surgery for bowel obstruction that was not due to recurrent disease, 3 had an episode of bowel obstruction that settled conservatively, and a further 5 underwent surgery for obstruction due to recurrent tumor. The presence of both a dose of abdominopelvic radiotherapy over 2250 cGy, as well as a second-look laparotomy prior to radiotherapy, was associated with an increased risk of serious bowel complications. The increased frequency of late bowel morbidity seen in the combined modality group is likely explained by the presence of these two factors, rather than the exposure to chemotherapeutic agents per se. These observations are supported by the published literature.

From 1974-1990, 23 women with stage I and five with stage II epithelial ovarian carcinoma received intraperitoneal chromic phosphate (32P) as the only form of adjuvant therapy after complete debulking and comprehensive surgical staging laparotomy. Surgery consisted of total abdominal hysterectomy with bilateral salpingo-oophorectomy, omentectomy, peritoneal washings for cytology, multiple biopsies of pelvic and abdominal peritoneum, and selective pelvic and para-aortic lymphadenectomy. Intraperitoneal 32P therapy was administered a median of 7 days after laparotomy. Significant toxicity was minimal; none of these patients required surgery for bowel obstruction. Overall 5-year survival was 90 and 100%, but disease-free survival was only 65% (95% confidence interval [CI] 36-86%) and 60% (95% CI 12-81%) for patients with stage I and II disease, respectively. Two patients developed intraperitoneal and six systemic relapses; all patients received cisplatin regimens after relapse. Univariate analysis of age, stage, histology, Ovarian Cancer Study/Gynecologic Oncology Group risk status, lesion size, and presence or absence of capsular adhesions revealed that only an age of 50 or more years had an adverse effect on disease-free survival (P less than .03). This study suggests that determination of early-stage disease and host-tumor biology may be the most important factors in determining the survival of women with early ovarian cancer defined by comprehensive surgical staging. Intraperitoneal 32P does not appear to be effective adjuvant therapy in these women.

One hundred four patients with ovarian cancer underwent intestinal reconstruction as part of a cytoreductive effort or for relief of intestinal obstruction from July 1980 to June 1990. Twenty-four percent of patients were obstructed preoperatively, while the remaining seventy-six percent had bowel resections performed in concert with a debulking procedure. The overall infectious complication rate was 14.4%. No statistical association was found between the presence of ascites at the time of laparotomy and infectious morbidity (P = 0.58). The use of a preoperative mechanical bowel preparation was associated with a significant reduction in infectious morbidity (P = 0.01). Additionally, patients considered in adequate nutritional condition experienced significantly less infectious complications than those patients in poor nutritional condition (P = 0.03). Intestinal procedures involving the large bowel were marginally associated with increased infectious complications (P = 0.13). Neither preoperative radiotherapy, the presence of preoperative obstruction, disease presence, extent of debulking, number of intestinal procedures, or hand versus stapled anastomosis was found to be significantly associated with infectious complications. It is concluded that the presence of ascites does not increase the infectious complication rate in ovarian cancer patients who undergo small or large bowel reconstructive procedures. Additionally, patients with preoperative bowel obstruction or previous abdominal radiation therapy were not found to experience a significant increase in the infectious complication rate in the current series.

Thirty advanced ovarian cancer patients have been treated with sequential multimodality treatment including primary surgery, cisplatin or carboplatin-based polichemotherapy, second-look laparotomy followed by abdominopelvic irradiation (moving strip or open-field technique). Toxicity related to the combined treatment was acceptable: only three patients failed to complete and two patients delayed the prescribed course of radiotherapy because of acute myelosuppression or gastroenteric disturbances. One patient without evidence of disease required laparotomy for bowel obstruction one month after completion of radiotherapy. No other chronic toxicity of clinical significance has been observed. Actuarial three-year survival significantly correlated with residual disease at the start of radiotherapy: no residuum, 100%, microscopic disease, 52%; less than 2 cm macroscopic disease, 27.4% (P less than 0.05), whereas recurrences were less frequent only in the group of pathological complete responders (3/9) compared to patients with limited disease (6/11 with micro and 7/10 with macroscopic residuum). In conclusion radiotherapy following surgery and chemotherapy is not associated to serious morbidity but its value in improving progression-free survival rates has to be tested in randomized trials.

From April 1983 through December 1989, 42 consecutive patients with diagnosis of epithelial ovarian carcinoma were initially managed by aggressive surgery and three courses of endoperitoneal cis-platinum-based chemotherapy followed by an alternating combination chemotherapy and second-look laparotomy. Patients with residual tumor less than or equal to 2 cm subsequently received whole abdominal radiation therapy (WAR). Twenty-eight patients (42% with no residual disease, 21% with microscopic disease, and 36% with residual disease less than 2 cm) were eligible for WAR. WAR was delivered using an open-field technique up to 22 Gy in 20 fractions followed by a pelvic boost of 18 Gy in 10 fractions. The kidneys were shielded posteriorly at 1100 cGy; hepatic shields were not added. One patient did not complete WAR for lung metastases after 5 radiotherapy fractions. The complete treatment program lasted 8 months (range, 6.8-11). The median follow-up of the 28 patients entered into the study was 50 months. Eight patients are alive and disease-free at 5 years. The overall and disease-free survival rates at 5 years are 45 and 30%, respectively. All but 2 patients relapsed within the abdominopelvic cavity and 3 developed brain metastases. Toxic effects, during WAR, required treatment interruption in all but 4 patients: 3 developed a small bowel obstruction requiring surgery and 1 died of surgical complications in complete remission. The poor disease-free survival and the severe toxicity encountered have been valid indications that WAR should be discontinued as a treatment modality in advanced ovarian cancer at our department.

The use of home parenteral nutrition (HPN) in patients with inoperable malignant bowel obstruction (IMBO) is controversial. The efficacy, safety, and indications for HPN in these patients is uncertain, and its benefit is difficult to demonstrate. The records of 17 patients (9, ovarian cancer; 4, colon cancer; 4, other) with IMBO receiving HPN managed by the Nutrition Support Team (NST) at Yale-New Haven Hospital from 1980 to 1989 were reviewed. Median survival was 53 days and was longest in the two patients with appendiceal carcinomatosis (208 and 159 days), intermediate in patients with colon cancer (median 90 days), and shortest in patients with ovarian cancer (median 39 days). Survival was unrelated to age or sex. All patients died of their underlying disease; 82% of deaths occurred at home. Only one treatment-related complication requiring readmission occurred. Fourteen patients and their families (82%) perceived their therapy as highly beneficial or beneficial. The NST agreed with this assessment in 11 patients but did not share this perception in three patients. These three patients had a short duration of HPN (less than 25 days) or minimal rehabilitation. It is concluded that HPN for patients with IMBO is associated with a low complication rate, may be most beneficial for those patients with gastrointestinal tract primary tumors, and is usually perceived by patients and care providers as beneficial. HPN has palliative benefit and facilitates compassionate home care for carefully selected patients with IMBO.
