Response To Chemotherapy

The objective of the study was to assess the feasibility of using CA -62 marker of epithelial carcinomas for monitoring treatment response and detecting cancer progression or recurrence during chemotherapy.Material and Methods. A 12-month double-blind clinical trial was conducted by two independent groups: clinical oncologists and biochemists, and involved 89 patients with different cancers confirmed by histopathological findings. The other inclusion criteria were: the presence of at least one measurable lesion according to the RECIST criteria, ECOG performance status 0-2 and satisfactory laboratory parameters. The expression of CA -62 cancer marker was measured by immunochemiluminescent assay used for the detection of epithelial carcinomas.Results. The elevated level of CA -62 marker was observed in 76 patients before starting the treatment. After completion chemotherapy, the level of this marker decreased to the normal reference ranges (<4600 U/ml) in 53 % of patients and remained increased in 24 % of patients. Of 24 % of patients with the initial low level of CA -62 marker (1000–4000 U/ml) before treatment, 12 % had no changes in the level of this marker during chemotherapy; however, 5 % of these patients had disease progression and 7 % had stable disease after starting the treatment. In 12 % of patients with an initial low CA -62 level, it increased during chemotherapy, indicating disease progression.Conclusion. The changes in the level of CA -62 marker during chemotherapy in patients with gastric cancer, small-cell lung cancer, colorectal cancer, neuroendocrine cancer and ovarian cancer showed a high correlation (76–100 % depending on the tumor site) with the performance status of the patients according to RECIST criteria. The CA -62 marker was shown to be feasible for monitoring gastric cancer, small-cell lung cancer, colorectal cancer, neuroendocrine cancer and ovarian cancer as well as for assessing the response to chemotherapy.

Her2 Positive

HER2 targeted therapies have significantly improved prognosis of HER2-positive breast and gastric cancer. HER2 overexpression and mutation is the pathogenic driver in non-small cell lung cancer (NSCLC) and colorectal cancer, however, to date, there are no approved HER2-targeted therapies with these indications. Trastuzumab deruxtecan (T-DXd) is a novel HER2-directed antibody drug conjugate showing significant anti-tumor activity in heavily pre-treated HER2-positive breast and gastric cancer patients. Preliminary data have shown promising objective response rates in patients with HER2-positive NSCLC and colorectal cancer. T-DXd has an acceptable safety profile, however with concerns regarding potentially serious treatment-emergent adverse events. In this review we focus on the pharmacologic characteristics and toxicity profile of T-Dxd, and provide an update on the most recent results of clinical trials of T-DXd in solid tumors. The referenced papers were selected through a PubMed search performed on 16 March 2021 with the following searching terms: T-DXd and breast cancer, or gastric cancer, or non-small cell lung cancer (NSCLC), or colorectal cancer. Oral presentation, abstracts, and posters presented at the American Society of Clinical Oncology (ASCO, Alexandria, VA, USA) 2020 and the European Society for Medical Oncology (ESMO, Lugano, Switzerland) 2020 annual meetings were retrieved for data on T-DXd. We also overview ongoing research and data of combination therapies currently under investigation, which will impact on future therapeutic strategies. Clinicaltrials.gov was searched to identify ongoing clinical trials of T-DXd alone or in combination in solid tumors.

PURPOSE Docetaxel (Taxotere, Rhone-Poulenc Rorer, Antony, France) and cisplatin are two of the most active single agents used in the treatment of non-small-cell lung cancer (NSCLC). A recently reported phase I study of the combination of docetaxel and cisplatin recommended a dose of 75 mg/m2 of both drugs every 3 weeks for subsequent phase II study. PATIENTS AND METHODS Eligible patients were aged 18 to 75 years with a World Health Organization (WHO) performance status < or = 2 and life expectancy > or = 12 weeks, with metastatic and/or locally advanced NSCLC proven histologically or cytologically. Patients were not permitted to have received prior chemotherapy, extensive radiotherapy, or any radiotherapy to the target lesion and must have had measurable disease. Concurrent treatment with colony-stimulating factors (CSFs) or prophylactic antibiotics was not permitted. Docetaxel (75 mg/m2) in 250 mL 5% dextrose was given intravenously (i.v.) over 1 hour immediately before cisplatin (75 mg/m2) in 500 mL normal saline given i.v. over 1 hour in 3-week cycles. Premedication included ondansetron, dexamethasone, promethazine, and standard hyperhydration with magnesium supplementation. RESULTS A total of 47 patients, two thirds of whom had metastatic disease, were entered onto this phase II study. The majority of patients were male (72%) and of good (WHO 0 to 1) performance status (85%). All 47 patients were assessable for toxicity and 36 were for response. Three patients were ineligible and eight (17%) discontinued treatment because of significant toxicity. In assessable patients, the overall objective response rate was 38.9% (95% confidence limits [CL], 23.1% to 56.5%), 36.1% had stable disease, and 25% progressive disease. On an intention-to-treat analysis, the objective response rate was 29.8%. Median survival was 9.6 months and estimated 1-year survival was 33%. Significant (grade 3/4) toxicities included nausea (26%), hypotension (15%), diarrhea (13%), and dyspnea mainly related to chest infection (13%). One patient experienced National Cancer Institute (NCI) grade 3 neurosensory toxicity after eight cycles. Grade 3/4 neutropenia was common and occurred in 87% of patients, but thrombocytopenia > or = grade 3 was rare (one patient). Significant (grade 3/4) abnormalities of magnesium levels were common (24%). Febrile neutropenia occurred in 13% of patients and neutropenic infection in 11%, contributing to two treatment-related deaths. No neutropenic enterocolitis or severe fluid retention was reported. CONCLUSION Compared with other active regimens used in this setting, the combination of docetaxel and cisplatin in advanced NSCLC is an active regimen with a similar toxicity profile to other combination regimens.
