AbstractBackground: The antimetabolic agent S-1 inhibits thymidylate synthase similar to pemetrexed, but through a different mechanism of action. Whether the antitumour activity of S-1 depends on histological type remains unclear. We analysed pooled data from 2 phase II clinical studies of cisplatin and S-1 in patients with previously untreated advanced non-small cell lung cancer. Patients and Methods: We comprised 110 patients with stage IIIB or IV non–small cell lung cancer. Univariate and multivariate analyses were performed to determine the effects of histological type on progression-free survival and response rates. Results: On pooled analysis of the data, according to histological type, median progression-free survival was 3.8 months in patients with squamous cell carcinoma and 4.4 months in those with non-squamous cell carcinoma. Both analyses showed that progression-free survival and response rate did not differ significantly. Conclusion: Unlike molecular targeted agents and pemetrexed, a combination of cisplatin and S-1 may be no difference in response according to histological type.

Abstract:
S-1, an oral fluoropyrimidine derivative, has been approved for the treatment of non-small cell lung cancer (NSCLC) in Japan. In the present study, the efficacy and safety of S-1 monotherapy for elderly patients with previously treated NSCLC were retrospectively evaluated, and the efficacy of S-1 monotherapy was compared by histopathological type. This retrospective study included 54 patients with advanced or recurrent NSCLC who had received S-1 monotherapy following the failure of previous chemotherapy regimens at our institutes. Patient outcomes were compared based on their age and histopathological type. S-1 was administered orally, twice daily, while the duration and interval were modified according to the medical condition of each patient. The default delivery schedule, the mean number of S-1 cycles, did not differ significantly between the two age groups (<70 and ≥70 years). The rate of therapy discontinuation, schedule modification or dose reduction due to intolerable toxicities or patient refusal was relatively frequent in the older group (40.7 and 55.6% for ages <70 and ≥70 years, respectively; p=0.414), and the incidence of grade 3 anemia was relatively high in the older group (3.7 and 18.5%, respectively; p=0.192). The response rates (13.0 and 4.8%, respectively; p=0.609) and disease control rates (39.1 and 33.3%, respectively; p=0.761) did not differ significantly between the two age groups. According to histopathological type, the disease control rate was significantly higher in adenocarcinoma (57.9%) compared to non-adenocarcinoma (20.0%, p=0.013). Thus, S-1 monotherapy may be equally effective and tolerated in patients <70 years and those ≥70 years. Additionally, adenocarcinoma may have a higher disease control rate than non-adenocarcinoma.

Abstract
Background: Previous small-sized studies showed lower thymidylate synthase (TS) expression in adenocarcinoma of the lung, which may explain higher antitumor activity of TS-inhibiting agents such as pemetrexed.
Patients and methods: To quantitatively measure TS gene expression in a large-scale Japanese population (n = 2621) with primary lung cancer, laser-captured microdissected sections were cut from primary tumors, surrounding normal lung tissues and involved nodes.
Results: TS gene expression level in primary tumor was significantly higher than that in normal lung tissue (mean TS/β-actin, 3.4 and 1.0, respectively; P < 0.01), and TS gene expression level was further higher in involved node (mean TS/β-actin, 7.7; P < 0.01). Analyses of TS gene expression levels in primary tumor according to histologic cell type revealed that small-cell carcinoma showed highest TS expression (mean TS/β-actin, 13.8) and that squamous cell carcinoma showed higher TS expression as compared with adenocarcinoma (mean TS/β-actin, 4.3 and 2.3, respectively; P < 0.01); TS gene expression was significantly increased along with a decrease in the grade of tumor cell differentiation. There was no significant difference in TS gene expression according to any other patient characteristics including tumor progression.
Conclusion: Lower TS expression in adenocarcinoma of the lung was confirmed in a large-scale study.

26日吃了12片地米（0.75mg一片），27日吃了22片地米（0.75mg 一片），28日吃了12片地米（0.75mg一片），都分二次吃。
今天为止没有任何反应，每天吃VC,VB2，还有漱口水，就怕口腔溃疡。
副作用如何，单药反应很小吧？

从4月24日开始到4月28日，打了5天的舒普深(注射用头孢哌酮钠舒巴坦钠),效果非常好。
至今为止，未出现化疗副作用。

没有副作用是第一追求，效果显著是第二追求。
不错。
