Anti Tumor Activity

The emergence of PD-1 antibodies has radically changed the therapeutic profiles of lung cancer, which has the highest incidence and mortality rate among all cancers worldwide. Pembrolizumab, an anti-PD-1 antibody, has been proven to have strong anti-tumor activity in a variety of clinical studies. Here, we described a patient with stage IIB squamous lung cancer who has benefited from a preoperative pembrolizumab plus chemotherapy regimen. The addition of pembrolizumab to neoadjuvant chemotherapy before surgery led to a pathologic complete response and the avoidance of left pneumonectomy. This case highlights the effect of neoadjuvant pembrolizumab plus chemotherapy on non-small cell lung cancer patients and has provided a promising choice in future clinical practice.

AbstractNeoadjuvant immunotherapy provides a unique opportunity for understanding therapeutic responses. We analyzed pathologic responses in surgical specimens obtained from 31 squamous non-small cell lung cancer (NSCLC) patients receiving neoadjuvant anti-PD-1 treatment. Fifteen (48.4%) patients achieved pathologic complete response (pCR) or major pathologic response (MPR). Among them, seven (46.7%) were assessed as radiological partial response and eight (53.3%) as stable disease. Among 20 patients with pathologically identified tumor beds in lymph nodes (LNs), 10 and six patients achieved pCR/MPR in primary tumors and paired LNs, respectively. pCR was achieved in 6/19 N1 nodes and 1/7 N2 nodes. Residual viable tumor (RVT) cells in 8/9 MPR specimens had 100% immune-activated phenotype, while a median of 80% of RVT cells in pathologic nonresponse specimens presented immune-excluded/desert phenotype. These findings demonstrated that assessment of pathologic responses in both primary tumor and LNs may be important as a surrogate for assessing neoadjuvant immunotherapeutic efficacy.

Favorable Prognostic Factor

7057 Background: Our study aimed to evaluate whether pathologic complete response (pCR) in early-stage non-small cell lung cancer (NSCLC) following neoadjuvant chemotherapy resulted in improved outcome and to determine predictive factors for pCR. Methods: Eligible patients with stage IB or II NSCLC were included in two consecutive Intergroupe Francophone de Cancérologie Thoracique (IFCT) phase III trials evaluating platinum-based neoadjuvant chemotherapy, with pCR defined by the absence of viable cancer cells in the resected surgical specimen. Results: Among the 492 patients analyzed, 41 (8.3%) achieved pCR. In the pCR group, 5-year overall survival (OS) was 80.0% compared to 55.8% in the non-pCR group (p=0.0007). In multivariate analyses, pCR was a favorable prognostic factor of OS (RR=0.34; 95% CI=0.18-0.64) in addition to squamous cell carcinoma (SCC), weight loss ≤5%, and stage IB disease. Five-year disease-free survival (DFS) was 80.1% in the pCR group compared to 44.8% in the non-pCR group (p<0.0001). Two patients (4.9%) in the pCR group experienced disease recurrence compared to 193 patients (42.8%) in the non-pCR group. SCC subtype was the only independent predictor of pCR (OR=4.30; 95% CI=1.90-9.72). Conclusions: Our results showed that pCR after preoperative chemotherapy was a favorable prognostic factor in Stage IB-II NSCLC. Our study is the largest published series evaluating pCRs following preoperative chemotherapy. The only factor predictive of pCR was SCC. Identifying molecular predictive markers for pCR may help in distinguishing patients likely to benefit from neoadjuvant chemotherapy and in choosing the most adequate preoperative chemotherapy regimen.

Purpose Population studies have suggested that metformin use in diabetic patients decreases cancer incidence and mortality. Metformin inhibits the growth of cancer cells in vitro and tumors in vivo. However, there is little clinical data to support this. Our purpose was to determine whether metformin use was associated with a change in pathologic complete response (pCR) rates in diabetic patients with breast cancer receiving neoadjuvant chemotherapy. Patients and Methods We identified 2,529 patients who received neoadjuvant chemotherapy for early-stage breast cancer between 1990 and 2007. Patients were compared by groups: 68 diabetic patients taking metformin, 87 diabetic patients not taking metformin, and 2,374 nondiabetic patients. pCR rates were compared between the three groups using χ2 tests of independence and compared pair- wise using a binomial test of proportions. Factors predictive of pCR were assessed using a multivariate logistic regression model. Results The rate of pCR was 24% in the metformin group, 8.0% in the nonmetformin group, and 16% in the nondiabetic group (P = .02). Pairwise comparisons between the metformin and nonmetformin groups (P = .007) and the nonmetformin and nondiabetic groups (P = .04) were significant. Comparison of the pCR rates between the metformin and nondiabetic groups trended toward but did not meet significance (P = .10). Metformin use was independently predictive of pCR (odds ratio, 2.95; P = .04) after adjustment for diabetes, body mass index, age, stage, grade, receptor status, and neoadjuvant taxane use. Conclusion Diabetic patients with breast cancer receiving metformin and neoadjuvant chemotherapy have a higher pCR rate than do diabetics not receiving metformin. Additional studies to evaluate the potential of metformin as an antitumor agent are warranted.

A patient with lung cancer carrying ROS1 translocation was treated by crizotinib and then subjected to surgery. Morphological analysis revealed pathologic complete response in surgically removed tissues, while PCR test provided convincing evidence for the presence of residual tumor cells. PCR analysis of lung cancer specific gene translocations allows carrying out highly sensitive and reliable monitoring of tumor disease during the course of treatment.

Abstract Introduction Among malignant diseases, lung carcinoma is the most common cancer in men worldwide in terms of both incidence and mortality. Its increasing incidence in developing countries like India is an important public health problem. This work aimed to study the demographic, clinical, radiological, and histological features of patients with confirmed lung cancer. Materials and Methods A total of 50 patients with histologically confirmed lung cancer at a tertiary care center in India from August 2016 to September 2018 were studied and analyzed. Results Out of 50 diagnosed lung cancer patients, 86% were men and 14% women; 31 (62%) patients were aged more than 60 years. Majority were smokers (84%) and all were men. Cough (94%) was the most common presenting symptom followed by dyspnea (68%), chest pain (48%), and hemoptysis (38%). Of the 50 patients, 29 (58%) had soft tissue density mass lesion on radiograph. Squamous cell carcinoma (SCC) was the diagnosed histological cell type in 24 (48%) patients and adenocarcinoma in 21 (42%) patients. Distant metastasis was observed in 20 (40%) patients. Conclusion In this study, the most common histopathological cell type is SCC. Patients aged more than 50 years and smokers are at high risk of lung cancer. Patients with a smoking history and persistent respiratory symptoms should be promptly evaluated for lung malignancy.

Our previous study indicated that a high amount of visceral adipose tissue was associated with poor survival outcomes in patients with early breast cancer who received neoadjuvant chemotherapy. However, inconsistency was observed in the prognostic role of body composition in breast cancer treatment outcomes. In the present study, we aimed to validate our previous research by performing a comprehensive body composition analysis in patients with a standardized clinical background. We included 198 patients with stage III breast cancer who underwent neoadjuvant chemotherapy between January 2007 and June 2015. The impact of body composition on pathologic complete response and survival outcomes was determined. Body composition measurements had no significant effect on pathologic complete response. Survival analysis showed a low ratio of total visceral adipose tissue to subcutaneous adipose tissue (V/S ratio ≤ 34) was associated with shorter overall survival. A changepoint method determined that a V/S ratio cutoff of 34 maximized the difference in overall survival. Our study indicated the prognostic effect of body composition measurements in patients with locally advanced breast cancer compared to those with early breast cancer. Further investigation will be needed to clarify the biological mechanism underlying the association of V/S ratio with prognosis in locally advanced breast cancer.
