Intrapatient Molecular and Histologic Heterogeneity After First-generation or Second-generation TKI Therapy of NSCLC Patients: Potential Clinical Impact on Subsequent third-generation TKI Treatment.

Objectives: The discovery of tyrosine kinase inhibitors (TKI) has remarkably improved the clinical course of patients with non-small cell lung cancer driven by Epidermal Growth Factor Receptor (EGFR) mutations. However, virtually in all cases, the disease resurfaces in a TKI-resistant form that is mainly linked to an acquired EGFR-T790M mutation, a MET amplification, or small cell lung cancer (SCLC) transformation. Third-generation TKIs are able to block tumor growth through an irreversible binding to the T790M-mutated receptor.

[A case of quadruple simultaneous second primary metachronous carcinomas subsequently involving colon, prostate, kidney and lung in an octogenarian patient].

The authors describe a case of quadruple second primary metachronous carcinomas subsequently occurred in an octogenarian patient: colon, prostate, kidney and, lastly, lung. No chemotherapy and or radiotherapy were given. Survival resulted three years after diagnosis of the first carcinoma and four years after the last carcinoma.

Epirubicin and gemcitabine as first-line treatment in malignant pleural mesothelioma.

Malignant pleural mesothelioma represents a rare disease, for which chemotherapy actually remains unsatisfactory. From August 1998 to November 2001, 28 chemo-radio-immunonaive patients were consecutively enrolled in the trial: 22/6 males/females; median age 63 years (range, 45-79); median ECOG PS 1 (range, 0-2). They were treated with epirubicin (100 mg/m2 iv on day 1) plus gemcitabine (1000 mg/m2 iv on days 1 and 8) every 4 weeks for 6 cycles.
