RESUMO

OBJECTIVES: Gastric cancer patients undergoing total gastrectomy face nutrition-related complications and worsening quality of life after surgery. In this context, gastrectomized cancer patients are required to cope with new conditions. Little is known about their accommodating feeding to the new life condition as a negotiated process among stakeholders in real contexts. This study aimed to investigate the shaping of this process as influenced by the perspectives of patients, health-care professionals (HPs), and caregivers (CGs). METHODS: A constructivist grounded theory study, through semi-structured interviews and interpretative coding, was designed to answer the following research question: "what is the process of returning to eating and feeding after a gastrectomy?" RESULTS: The final sample included 18 participants. "Defining a balance by compromising with fear" is the core category explaining returning to eating as a process negotiated by all actors involved, with patients trying to find a feeding balance through a multi-layer compromise: with the information received by HPs, the proprioception drastically altered by gastric resection, new dietary habits to accept, and complex and often minimized conviviality. This process involves 4 main conceptual phases: relying on the doctors' advice, perceptive realignment, rearranging food intake, and food-regulated social interaction. Those categories are also shaped by the fear of being unwell from eating and the constant fear of tumor relapse. SIGNIFICANCE OF RESULTS: Multiple actors can meet patients' and their CGs' nutritional, care, and psychosocial needs. A multidisciplinary approach involving nutritionists, psychologists, occupational therapists, social workers, and anthropologists can be key to effectively managing these patients' survivorship care. We suggest training all the professionals on the first level of nutritional counseling.

RESUMO

AIMS: Identification of epidermal growth factor receptor (EGFR) mutations in lung adenocarcinomas is the single most important predictor of clinical response and outcome using EGFR tyrosine kinase inhibitors (TKIs). EGFR E746-A750del and L858R mutations are the most common gene alterations, also predicting the best clinical response to TKIs. We evaluated the accuracy of EGFR mutation-specific antibodies in a large cohort of lung adenocarcinomas, with different molecular settings and types of tissue samples. METHODS: 300 lung adenocarcinomas diagnosed on cytology (48 cell blocks), biopsy (157 cases) and surgical resections (95 cases) were selected. All cases were investigated for EGFR by sequencing and two mutation-specific antibodies (clone 6B6 for E746-A750del; clone 43B2 for L858R) were tested using an automated immunostainer. Discordant results were investigated by next-generation sequencing (NGS). RESULTS: Overall sensitivity and specificity of mutant-specific antibodies were 58.6% and 98.0%, respectively, and they increased up to 84% and 100% if only tumours harbouring E746-A750del were considered. In 13 discordant cases, NGS confirmed immunohistochemistry results in eight samples. CONCLUSIONS: The EGFR mutation-specific antibodies have a fair/good sensitivity and good/high specificity in identifying classic mutations, but they cannot replace molecular tests. The antibodies work equally well on biopsies and cell blocks, possibly permitting a rapid screening in cases with poor material.

RESUMO

OBJECTIVES: Combination chemotherapy is very active in small cell lung cancer (SCLC), although no improvement in overall survival (OS) has been done in the last 25 years, with Cisplatin-Etoposide (PE) still considered the world-wide standard, with an average median survival of about 7-8 months in patients with extended disease (ED). In 1995, a randomized trial of the Hoosier Group in 171 ED patients showed a significant advantage in overall survival in patients treated with PEI (Cisplatin, Etoposide and Ifosfamide), compared to PE. Despite that, PEI regimen has not become a commonly used regimen in SCLC. MATERIALS AND METHODS: Here we present a retrospective analysis of 46 consecutive patients (30 males and 16 females) with SCLC that were treated at our Institution with PEI regimen: Cisplatin 20 mg/m2, Etoposide 75 mg/m2 and Ifosfamide 1200 mg/m2, day 1 to 4, every 3 weeks. Patients received a total of 219 cycles of chemotherapy, with a mean of 4,7 cycles per patient. Median age was 63 (range 59-70); performance status (PS) was 0 in 29 patients (63%), 1 in 13 patients (28%) and 2 in 4 patients (9%). RESULTS: In 19 limited disease (LD) patients partial response (PR) rate was 74%, and complete response (CR) was 16%. In 27 ED patients we observed 63% of PR and 26% of CR. Median time to progression (TTP) was 15.2 months in LD and 7.1 months in ED with median overall survival (OS) of 28.2 and 11.8 months, respectively. Toxicity was manageable, with a high dose intensity. CONCLUSIONS: PEI regimen, in our opinion, may be a possible therapeutic option, with high activity and an acceptable toxicity profile.

RESUMO

Oncogenic drivers in lung non-small-cell lung cancer (NSCLC) are considered mutually exclusive, but a review of the literature reveals that concomitant EGFR mutations and ALK rearrangement may occur in a subset of NSCLC. We report here a case of pulmonary adenocarcinoma with concomitant EGFR mutation in exon 21 (L858R) and ALK rearrangement in naive and relapsed tumors. Tumor cells seem to harbor both gene alterations and the patient had a long-lasting response both to EGFR inhibitor in second line and ALK inhibitor once tumor progressed. A speculative discussion on molecular mechanisms underlying this uncommon phenomenon and practical points about epidemiologic, clinicopathologic features and therapeutic options in this intriguing subset of double-positive tumor are reported.
