Antigen expression by human small cell lung carcinoma cells in serous effusions was determined by staining smears of cells with a panel of four monoclonal antibodies including UJ13A (cluster 1 antigen) and CAM 5.2 (anti-cytokeratin) using an immunoalkaline phosphatase technique. This was quantified by counting the proportion of stained and unstained tumour cells and was compared with that of small cell lung carcinoma in sections of solid tumour. Differential expression of antigen expression was noted with significantly fewer small cell carcinoma cells in serous effusions staining with UJ13A or CAM 5.2. The reasons for this differential expression are unknown, but may reflect adaptation to a different environment or be a prerequisite for spread to serous space.

From October 1979 to December 1982, 126 patients with locally advanced unresectable or inoperable Stage II (7 patients), Stage IIIA (81 patients), and Stage IIIB (38 patients) non-small cell carcinoma of the lung were treated in a prospective randomized trial using five cycles of CAP (Cytoxan, Adriamycin, and cisplatin), T-CAP (triazinate plus CAP), or V-CAP (VP-16 plus CAP) chemotherapy with thoracic radiation therapy (TRT). TRT consisted of 40 Gy in 10 fractions (split-course) with cycles 3 and 4 of chemotherapy. The treatment field included the primary tumor, ipsilateral hilum, mediastinum, and ipsilateral supraclavicular fossa. All patients were followed until death or for a minimum of 5 years for survivors. The evaluable subgroup consisted of 102 patients who completed TRT. Median and 5-year survivals for the entire group were 14.0 months and 10%, respectively; for the evaluable subgroup, they were 14.8 months and 12%, respectively. There was a trend toward better survival with V-CAP plus TRT than with CAP plus TRT (p = 0.08). Median and 5-year survivals were 16.2 months and 18%, respectively, with V-CAP plus TRT. Of eight prognostic variables analyzed for their association with survival, only Eastern Cooperative Oncology Group performance status (0,1 versus 2) (p = 0.02) and weight loss (less than or equal to 10% versus greater than 10%) (p = 0.05) were significant. Sex, age, T stage, N stage, overall stage, and histologic type were not significantly associated with survival. Failure analysis revealed 83 patients (81%) with identifiable first failures. The median time to first failure was 9.8 months, and the median survival after first failure was 4.7 months. Failure patterns included local failure alone (19%), local and distant (20%), and distant alone (43%). Nineteen percent of patients had no documented progression. Total failure patterns were local in 39% and distant in 63%. Twenty-three patients (23%) had failure in the brain; they accounted for 31% of all distant failures. In 20 of these patients (20% of all patients), this was the only site of failure. There were eight (8%) initial nodal failures in 96 untreated contralateral supraclavicular fossae. No initial failures were seen in any of 101 untreated contralateral hila. The data suggest the following: (a) Combined treatment with V-CAP and TRT yielded excellent results (median survival, 16.2 months; 5-year survival, 18%).(ABSTRACT TRUNCATED AT 400 WORDS)

In two different controlled prospective randomized trials the Lung Cancer Study Group has shown that adjuvant CAP chemotherapy is effective in prolonging the disease-free survival. These studies indicate that the adjuvant chemotherapy has its effect by way of diminishing systemic recurrences and that the adjuvant therapy is more effective in non-squamous than in squamous disease. In addition, the benefit of the treatment is more apparent in patients with more advanced, though resectable, disease. It is also becoming clear that chemotherapy either alone or in combination with radiation therapy can result in relatively high response rates in patients with disease localized to the thorax. Indeed, many of these individuals can then undergo surgical resection. It remains to be determined, however, whether or not this preoperative therapy will be effective in prolonging survival. In the future it is quite likely that optimum therapy will involve the use of preoperative treatment either with chemotherapy alone or a combination of chemotherapy and radiation therapy, followed postoperatively with adjuvant chemotherapy with a non-cross resistant regimen. In addition, a major problem is brain recurrences. Indeed the brain was the most frequent site of first recurrence systemically in many of these studies. Thus, more effective therapy directed at CNS disease will have to be developed before major breakthroughs can be anticipated in the surgical adjuvant therapy of lung cancer.

The Lung Cancer Study Group randomized 141 patients with resected stage II and III adenocarcinoma and large-cell undifferentiated carcinoma to receive postoperative Cytoxan (Bristol-Meyers, Syracuse, NY), Adriamycin (Adria Laboratories, Columbus, Ohio), and cisplatin (CAP) chemotherapy or bacillus Calmette-Guerin (BCG) and levamisole immunotherapy. Careful intraoperative staging was performed on all patients. Before randomization, patients were stratified by stage, weight loss, cardiac arrhythmia, and institution. Prognostic variables such as stage, age, weight loss, and nodal involvement were equally distributed between the two groups. Disease-free survival was significantly prolonged in the group receiving chemotherapy. There was no evidence of a deleterious effect of the immunotherapy. This study indicates that postoperative CAP chemotherapy is effective in prolonging disease-free survival in these patients.

Sixty patients with advanced squamous cell lung carcinoma were entered in a study comparing the effectiveness of BACON and CAP combination chemotherapy. The CAP regimen was superior to the BACON regimen in response rate (50% vs 33%), median survival time (36 vs 24 weeks), and median time to progression (25 vs 16 weeks). Median survival time for responders was longer in both treated groups than for nonresponders. Side effects were significant, but generally reversible. This study seems to indicate a role for the CAP combination (cyclophosphamide, adriamycin, cisplatinum) as treatment for patients with squamous cell lung carcinoma.

Thirty-four previously untreated patients with histologically proven small cell carcinoma of the lung were treated with a combined modality therapy program that incorporated VP16-213, an epipodophyllotoxin derivative, into the chemotherapy regimen. Initial therapy for two cycles was with V-CAM, VP16-213, cyclophosphamide, doxorubicin and methotrexate. Following two cycles of V-CAM each patient received radiation therapy consisting of 4000 rads to the primary site, both hila and the mediastinum, as well as 2000 rads as prophylaxis to the whole brain. After a one-week rest period the patients received monthly cycles of V-CAM until death. Of 10 patients with stage IIIM0 disease, 7 had a complete response (CR), 1 a partial response (PR) and 2 had progressive disease. The median survival was still not reached by approximately 18 months. Of 24 patients with supraclavicular and/or metastatic disease there were only 5 patients with a CR, 11 with a PR and 8 with progressive disease. Their median survival was approximately 9 months. The 70% overall response rate and 9.3-month median survival of the entire group are essentially the same results as those in previously reported studies. There appears to be no additional benefit when VP16-213 is incorporated into our combined modality program.

A newly synthesized mycophenolic acid (MPA) derivative, ethyl O-[N-(p-carboxyphenyl)-carbamoyl]-mycophenolate (CAM, NSC-297879D) was tested for antitumor activity, when given orally, against transplantable murine tumors. The compound was markedly effective against transplantable murine tumors. The compound was markedly effective against leukemia P388 and L1210, lymphoma L5178Y, mastocytoma P815 and sarcoma Meth-A, moderately effective against sarcoma-180, C3MC2 and BAMC1, Ehrlich carcinoma, Lewis lung carcinoma and melanoma B16 and marginally effective against hepatoma MH134. The antitumor effects were manifested not only in growth inhibitory effects on subcutaneously transplanted tumors but also in the prolongation of life span of mice int which the tumors had been inoculated intraperitoneally or subcutaneously. The growth of primary transplants of a mammary tumor which developed spontaneously in a C3H/He mouse was inhibited by consecutive administration of CAM frm the 34th day after the transplantation. Oral CAM was more potent than its mother compound, MPA, in the tumor models examined. These results indicate that orally administered CAM has a wide antitumor spectrum.

The overall 5-year survival of surgically resected non-small cell lung cancer (NSCLC) remains less than 50% and is unlikely to improve until there are effective systemic adjuvant therapies. Two studies of the Lung Cancer Study Group (LCSG) have shown a modest impact of adjuvant CAP chemotherapy on disease-free and overall survival. In addition, a Finnish study, which randomized patients with T1-T3, N0 disease to CAP chemotherapy or follow-up, has also demonstrated an improvement in recurrence-free survival, as well as overall survival, at 5 and 10 years. On the other hand, an LCSG trial of adjuvant CAP in Stage I NSCLC (T2, N0, T1 N1) showed no benefit, although compliance with treatment was poor. Similarly, adjuvant trials using vindesine and cisplatin have not demonstrated benefit in studies done in Montreal and New York. Clearly, more effective systemic therapy is needed and must be evaluated in randomized trials in which patients have been carefully staged intra-operatively. Biological markers, such as vascular invasiveness, oncogene mutations and other factors may allow identification of specific subsets of patients at high risk of recurrence who can be targeted for aggressive adjuvant approaches in the future.

Disseminated micrometastatic disease limits the effectiveness of even the most aggressive locoregional treatment strategies in patients with early stage non-small cell lung cancer. One trial of the Lung Cancer Study Group (LCSG) demonstrated a significant decrease in the hazard rate for distant recurrence produced by adjuvant CAP chemotherapy after surgical resection and radiation therapy. French investigators found a significant decrease in distant metastases formation following sequential chemotherapy, radiation, and then additional chemotherapy compared to radiation alone in patients with stage III disease. However, other completed trials are either inconclusive, incompletely analyzed thus far or show no evidence of an effect of adjuvant chemotherapy on distant metastases. Additional data from recently completed or current trials will hopefully clarify the impact of adjuvant chemotherapy on distant micrometastases in patients with potentially curable non-small cell lung cancer (NSCLC).

In order to improve the diagnosis of lung carcinoma, in which a complicated histologic pattern is present, the immunohistochemistry of 119 adenocarcinomas, 65 squamous cell carcinomas, 12 small cell carcinomas, 18 large cell carcinomas, and 15 metastatic adenocarcinoma in the lung were evaluated using a monoclonal antibody, KM195, against lung carcinoma, and compared with the immunohistochemical results using anti-human cytokeratin (CAM 5.2) and other monoclonal antibodies. Formalin-fixed, paraffin-embedded tissues were stained using the labeled streptavidin-biotin method. Extracts from fresh tissue homogenate, after fractionation by sodium dodecyl sulfate-polyacrylamide gel electrophoresis, were transferred by Western blotting and stained with KM195. The anti-lung adenocarcinoma, murine, monoclonal antibody KM195 (IgG), was positive in 107 of 119 adenocarcinomas (90%), in 15 of 18 large cell carcinoma (83%), in three of 65 squamous cell carcinomas (5%), 13 of 15 (87%) metastatic adenocarcinoma in the lung, and was negative in 12 small cell carcinomas (P < 0.001). KM195-bound protein of primary and metastatic adenocarcinoma in the lung cases concentrated at about 40 kDa. In contrast, CAM 5.2 was positive in 52 of 67 (78%) adenocarcinomas, 10 of 62 (16%) squamous cell carcinomas, and was negative in six small cell carcinomas. These results suggest that the immunohistochemistry for KM195 may be a more useful marker over CAM 5.2 for the diagnosis of pulmonary adenocarcinoma.
