Four cycles of chemotherapy and regional radiation therapy for clinical early-stage and intermediate-stage Hodgkin's disease.

To achieve a high percentage of durable complete remissions (CR) and prolonged survivals and reduce toxicity in patients with early-stage and intermediate-stage Hodgkin's disease, a randomized trial of four cycles of mechlorethamine, vincristine, procarbazine, and prednisone (MOPP) versus four cycles of thiotepa, bleomycin, and vinblastine (TBV) combined with regional radiation therapy (RT) was conducted. For MOPP and RT, the CR percentage was 98% (60 of 61), and at 5 years, the percentage of patients in CR was 90%, with freedom from progression of 89% and overall survival of 91%. For TBV and RT, the CR percentage was 93% (55 of 59), with a 5-year duration of CR of 83%, freedom from progression of 81%, and overall survival of 91% (P greater than 0.15). The median follow-up was 65 months (range, 7 to 96 months). For 27 patients with clinical Stage IIIA, the CR percentage for MOPP and RT was 75% (12 of 16), with 1 relapse and 4 deaths. For TBV and RT, the CR percentage for clinical Stage IIIA was 73% (8 of 11) with 2 relapses and 2 deaths. Short-term toxicity except for transient leukopenia was less for TBV and RT than for MOPP and RT. Good results are achievable with combined treatment without excessive toxicity.

Impact of adjuvant radiation on the patterns and rate of relapse in advanced-stage Hodgkin's disease treated with alternating chemotherapy combinations.

The role of adjuvant radiation therapy (RT) in the management of advanced-stage Hodgkin's disease (HD) was analyzed in 222 patients who attained a complete remission (CR) with alternating chemotherapy combinations. Mechlorethamine, vincristine, procarbazine, and prednisone/doxorubicin, bleomycin, vinblastine, and dacarbazine (MOPP/ABVD) or MOPP/ABV alternating with the lomustine, melphalan, and vindesine combination (MOPP/ABV/CAD) were similarly effective in inducing a CR in 222 of 270 (83%) patients. These patients were scheduled to receive consolidative RT to bulky disease or other critical sites of initial nodal involvement to a total dose of 2,000 cGy, with an optional additional boost of 1,000 cGy. However, only 125 (56%) patients received radiation to all initial nodal sites of disease. In 69 (31%) patients, only selected nodal sites were included in the radiation fields, and 28 (13%) did not receive any RT. Of the 222 CR patients, 42 (19%) relapsed during a median follow-up period of 6.5 years (range, 2 to 15 years). Of these, 26 (62%) patients relapsed exclusively in unirradiated nodal sites, six (14%) within irradiated sites, and 10 (24%) both within and outside irradiated fields. The actuarial 10-year relapse-free survival (RFS) and overall survival (OS) for patients receiving radiation to all initially involved nodal sites were 89% and 94%, respectively, compared with 68% and 71% (P less than .0001) for patients who had only partial or no RT. Cox proportional hazards regression analysis showed that RT to all sites of initial disease was the most significant independent covariate (P less than .005) affecting RFS and OS. These data demonstrate that residual microscopic disease is relatively frequent in patients with apparent CR after alternating combination chemotherapy, and that irradiation of all sites of initial nodal involvement decreases relapse and improves survival in advanced-stage HD.

Actuarial Analysis

A prospective study of the accuracy of preoperative computed tomographic staging of patients with biopsy-proven rectal carcinoma.

From June 1983 to January 1986, 91 patients with biopsy-proven adenocarcinoma of the rectum had computed tomographic scans of the pelvis performed before treatment as part of a "sandwich" radiotherapy-surgery regimen. Two experienced diagnostic radiologists performed locoregional staging of all scans according to the University of California at San Francisco criteria; one of these radiologists repeated this staging at a later time to test the reproducibility of a single observer. Staging was performed without the use of any other radiographic studies or of any clinical information except the patients' age, sex, and the diagnosis of rectal carcinoma, to test the value of computed tomographic scans alone for staging. Agreement between the two stagings performed by the first observer was 51 percent, and interobserver agreement was only 37 percent. Agreement with Dukes' staging was only 33 percent. Therefore, preoperative pelvic computed tomographic scanning of primary rectal adenocarcinoma should not be relied upon for staging or for the selection of patients for treatment options.

Prognostic factors among 185 adults with newly diagnosed advanced Hodgkin's disease treated with alternating potentially noncross-resistant chemotherapy and intermediate-dose radiation therapy.

The initial promising results with alternating chemotherapy regimens (mechlorethamine, vincristine, procarbazine, and prednisone/doxorubicin, bleomycin, vinblastine, and dacarbazine [MOPP/ABVD]; lomustine, melphalan, and vindesine [CAD] plus MOPP plus ABV) combined with intermediate-dose radiation therapy (RT) have been sustained with further follow-up; 82.2% of patients (152 of 185) achieved a complete remission (CR), and overall survival is 71.7% +/- 4.4% at 8 years (median follow-up is 55 months among the survivors). No statistically significant differences were found in CR percentage, CR duration, or survival between stages IIB, IIIB, and IV patients. For that reason, stepwise Cox regression analyses to identify the important prognostic factors were performed on overall survival, tumor mortality, freedom from disease progression, and survival following disease progression. Pretreatment characteristics were also tested for association with the probability of achieving CR, CR duration, and death due to other causes. Characteristics that were consistently associated with an independently unfavorable prognosis were low hematocrit, high serum lactic acid dehydrogenase (LDH), age more than 45 years, inguinal node involvement, mediastinal mass greater than .45 of the thoracic diameter, and bone marrow involvement. Patients with two or more unfavorable characteristics were much more likely to fail treatment (median survival, 62.4 months) than those with none or only one unfavorable factor (greater than 95% survival). This striking difference between the low- and high-risk groups remained even if the comparison was restricted to patients less than or equal to 45 years of age. These results provide a basis for selecting the young patients at high risk of failure for more intensive initial treatment with either autologous bone marrow rescue or hematopoietic growth factors.

Benign persistent pneumoperitoneum in scleroderma.

We present a 68-year-old patient who, over a two-year period, was observed to have persistent benign pneumoperitoneum. The free air was present in the abdominal cavity without gastrointestinal perforation or pneumatosis cystoides intestinalis. The persistent pneumoperitoneum was a benign process and was not associated with peritonitis or other ill effects. The source of the free air was not clear. Conceivably, microperforations occurring in colonic diverticula or in distended intestinal wall induced the persistent benign pneumoperitoneum.

Treatment of stages I and II Hodgkin's disease with three different therapeutic modalities.

Since 1969, 184 previously untreated and evaluable adult patients with Hodgkin's disease, staged as I (43) or II (141), have been treated. Eighty patients were part of the National Hodgkin's Disease Study, randomly assigned to receive radiotherapy to either an involved (39) or extended field (41). In a subsequent single-arm study, 104 patients were treated with involved-field radiotherapy preceded and followed by three cycles of MOPP chemotherapy. Median durations of follow-up have been 172, 172, and 92 months, for the involved-field radiotherapy, extended-field radiotherapy, and MOPP plus involved-field radiotherapy treatment groups, respectively. Although significant differences among the three treatment groups were observed with respect to disease-free survival (p less than 0.001), only the group of patients treated with involved-field radiotherapy had a statistically significant decline in overall survival as compared with the two other treatment groups (p less than 0.001). Moreover, patients who underwent clinical staging and were treated with MOPP plus involved-field radiotherapy had significantly prolonged disease-free survival compared with those who underwent surgical staging and were treated with extended-field radiotherapy (p less than 0.001). One of the patients who received MOPP plus involved-field radiotherapy had subsequent development of acute monocytic leukemia, and another had refractory anemia with excess blasts. One instance of diffuse poorly differentiated lymphocytic lymphoma was also observed. Acute monocytic leukemia developed in another patient treated with involved-field radiotherapy. The rates of amenorrhea in the group treated with MOPP plus involved-field radio-therapy were 9.6 percent and 78.5 percent for female patients younger and older than 30 years of age, respectively. Despite the universal azoospermia ensuing after MOPP plus involved-field radiotherapy, in three patients whose sperm counts were checked sequentially for 26 to 53 months after treatment, evidence of spermatogenesis was observed. Three patients with remission of Hodgkin's disease after involved-field (two) and extended-field (one) radiotherapy died from cardiovascular disease that could only be attributed to the prior radiotherapy. Although further follow-up evaluation will be required to determine the impact of the three different treatment modalities on survival and long-term toxicity, MOPP plus involved-field radiotherapy appears to be superior to involved-field or extended-field radiotherapy alone in achieving prolonged disease-free survival without significant leukemogenic potential.

Comparative merits of conventional, computed tomographic, and magnetic resonance imaging in assessing mediastinal involvement in surgically confirmed lung carcinoma.

Thirty-four patients with operable malignant tumors of the lung had computed tomography and magnetic resonance imaging of the chest in addition to regular chest roentgenograms and bronchoscopy. The purpose of the study was to assess the extent of tumor involvement in the hilum and the mediastinum by direct invasion and by regional lymph node metastasis. At thoracotomy, 23 tumors were completely resected and 11 were treated by interstitial implantation of radioisotopes. In addition, a mediastinal lymph node dissection or sampling was performed to correlate nodal involvement with the preoperative studies. The tumor was peripheral in 21 patients and central in 13. Histologically, 18 tumors were adenocarcinomas, 14 epidermoid cancers, and two atypical carcinoids. Preoperatively, 18 tumors were classified as N0 disease, nine as N1, and seven as N2. Pathologically, 11 were N0, eight N1, and 15 N2. Plain chest roentgenograms correlated poorly with the nodal findings at operation. Both magnetic resonance and computed tomographic imaging were highly accurate in assessing the hilum and the presence of mediastinal adenopathy, with a sensitivity rate of 87%. Except for identifying contact with the mediastinum, neither method correlated well with mediastinal invasion when present (sensitivity rate 55% for computed tomography and 64% for magnetic resonance) and neither method could differentiate hyperplastic from metastatic nodes. Hence, no advantage of magnetic resonance over computed tomographic scanning was noted in assessing tumor involvement of the mediastinum by direct invasion or by regional lymph node metastasis.
