Abstract Background: The skull is an uncommon site for bone metastasis of lung cancer. The most common type of skull metastasis is calvarial circumscribed intraosseous lesions. However, the use of targeted therapy or surgery remains controversial and the prognosis is poor.Case presentation: Skull metastasis was detected in a woman 4 years after resection of non-small cell lung cancer. Despite targeted drug therapy, the tumor continued to grow. However, the patient refused surgical treatment until she developed neurological deficit. An epidural effusion occurred after the operation. The patient was followed up for 16 months and her condition remained stable.Conclusion: Skull metastases of lung cancer can grow invasively. The current and previously reported cases highlight the importance of prompt removal of tumors located in the calvaria.

The Cost

Aim: to conduct a pharmacoeconomic analysis of chemotherapy taking into account the types of malignant neoplasms of the bronchi and lung, and to calculate pharmacoeconomic efficiency.Materials and methods. The materials for the study were the data of the Moscow Cancer Hospital n.a. D.D. Pletnev for 2019. The cost of drugs was calculated according to the data of the website aptekamos.ru (for June 2019).Results and discussion. For 300 patients with squamous non-small cell lung cancer, it is required 3205.5 courses of chemotherapy of I (1747.5) and II (1458) lines. For 200 patients with non-small cell non-squamous EGFR positive lung cancer, it is required 1,413.1 courses of chemotherapy and targeted therapy. For 70 patients with non-squamous cell non-small cell lung cancer with ALK mutation, it is required 450.2 courses of chemotherapy and targeted therapy. For 280 patients with non-squamous cell non-small cell lung cancer lung cancer without mutations, it is required 7515 chemotherapy courses. For 150 patients with small cell lung cancer, it is required 1,656.8 courses of chemotherapy. Thus, a total sample of 1000 patients, excluding the type of malignant neoplasm of broncus and lung are required 14,239.8 chemotherapy courses. The determined cost of 67,000 rubles for the average chemotherapy course per patient takes into account the necessary colony stimulating factors, antiemetic, infusion solutions, etc.; in the case of treatment with erlotinib (the length of the course is 8 months), the cost is 663,408.0 rubles; in the case of treatment with crizotinib (the length of the course is 11 months course), the cost is 2044110.0 rubles. The average cost of drug therapy for one patient with malignant neoplasm of bronchus and lung is 1136155.9 rubles.Conclusion. We determined the pharmacoeconomic dependence of a chemotherapy on the type of malignant neoplasms of bronchus and lung and the main anticancer drug used. The median of the overall survival rate of patients with malignant neoplasms of bronchus and lung was 42 months. The average cost of drug therapy was 27051.3 rubles per month. The median survival rate without therapy is 3 months. Thus, therapy can extend the patient’s life by an average of 39 months. The cost of a month of a saved life is 29132.2 rubles.

AbstractSmall cell lung cancer (SCLC) remains a deadly form of cancer, with a 5-year survival rate of less than 10 percent, necessitating novel therapies. Receptor tyrosine kinase-like orphan receptor 1 (ROR1) is an oncofetal protein that is emerging as a therapeutic target and is co-expressed with BCL2 in multiple tumor types due to microRNA coregulation. We hypothesize that ROR1-targeted therapy is effective in small cell lung cancer and synergizes with therapeutic BCL2 inhibition. Tissue microarrays (TMAs) and formalin-fixed paraffin-embedded (FFPE) SCLC patient samples were utilized to determine the prevalence of ROR1 and BCL2 expression in SCLC. Eight SCLC-derived cell lines were used to determine the antitumor activity of a small molecule ROR1 inhibitor (KAN0441571C) alone and in combination with the BCL2 inhibitor venetoclax. The Chou-Talalay method was utilized to determine synergy with the drug combination. ROR1 and BCL2 protein expression was identified in 93% (52/56) and 86% (48/56) of SCLC patient samples, respectively. Similarly, ROR1 and BCL2 were shown by qRT-PCR to have elevated expression in 79% (22/28) and 100% (28/28) of SCLC patient samples, respectively. KAN0441571C displayed efficacy in 8 SCLC cell lines, with an IC50 of 500 nM or less. Synergy as defined by a combination index of <1 via the Chou-Talalay method between KAN0441571C and venetoclax was demonstrated in 8 SCLC cell lines. We have shown that ROR1 inhibition is synergistic with BCL2 inhibition in SCLC models and shows promise as a novel therapeutic target in SCLC.

Globally, lung cancer is the leading cause of cancer-related death. The majority of non-small cell lung cancer (NSCLC) tumours express epidermal growth factor receptor (EGFR), which allows for precise and targeted therapy in these patients. The dysregulation of EGFR in solid epithelial cancers has two distinct mechanisms: either a kinase-activating mutation in EGFR (EGFR-mutant) and/or an overexpression of wild-type EGFR (wt-EGFR). The underlying mechanism of EGFR dysregulation influences the efficacy of anti-EGFR therapy as well as the nature of resistance patterns and secondary mutations. This review will critically analyse the mechanisms of EGFR expression in NSCLC, its relevance to currently approved targeted treatment options, and the complex nature of secondary mutations and intrinsic and acquired resistance patterns in NSCLC.
