The results of the MVA are shown in Table 1. Moreover, reducing the number of variables to 2 factors (stage and tumor site) (Table 2), the results, once again, are confirmed. Stage and tumor site remain independent predictors of overall survival (OS). To test the validity of the model and answer the second question by Wang et al.,2 considering the small sample of the population, we implemented the analysis including the cross-validation with bootstrapping. To quantify the discrimination performance of the model, Harrell’s C-index was measured. The model was subjected to bootstrapping validation (1000 bootstrap resamples) to calculate the optimistic corrected estimate of C-index. The C-index for OS models was 0.70 while the corrected C-index was 0.67. Despite the small sample, the conclusions of our model seem to be robust. The potential for significant bias has already been mentioned in our report1 and the results must be considered cautiously. Large-scale studies are warranted.","PeriodicalId":23450,"journal":{"name":"Tumori Journal","volume":"14 1","pages":"532 - 532"},"PeriodicalIF":0.0,"publicationDate":"2019-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89104142","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The authors aimed to evaluate clinical outcome of patients diagnosed with small bowel adenocarcinoma. They drew the conclusion that disease stage and primary tumor site were independent predictors of overall survival. However, some statistical problems need to be resolved before drawing that conclusion. The author mentioned in the article that multivariate Cox regression was used to test independence of significant factors in univariate analysis. All the variables (including nonsignificance factors) in the univariate analysis were imported into the multivariate regression model, resulting in an inevitable problem with overparameterization.2,3 As we know, age is a factor closely related to tumor incidence and progression. In this multivariate Cox regression, age was presented as nonsignificant, maybe caused by overparameterization. Therefore, we suggest excluding the sex factor from multivariate Cox regression. Another important question, especially in studies with small sample size, is the validity of the prediction model. This seems to be the major limitation of the Rosa Falcone et al. study, and it can be solved with statistical methods such as cross-validation and bootstrapping.4 Otherwise, the authors could draw an incorrect conclusion.","PeriodicalId":23450,"journal":{"name":"Tumori Journal","volume":"36 1","pages":"531 - 531"},"PeriodicalIF":0.0,"publicationDate":"2019-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77872529","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we found that the proportion of collapsed microvessels is suggested to be a novel biomarker for predicting prognosis in patients with non-small cell lung cancer (NSCLC). Methods: In this study, immunohistochemical CD31 staining was performed to identify the microvessels in tumor specimens. Proportions of collapsed vessels were estimated in CD31-stained tumor specimens from 100 patients with NSCLC. The correlation between collapsed microvessel proportion and survival time were evaluated by univariate and multivariate analysis. Results: Data from 99 patients were analyzed and a wide range of collapse–microvessel fraction was observed in 96 patients (1.4%–70%).

We present our preliminary experience with the use of the i-gel O2 supraglottic airway device for management of EBUS procedures. Methods: An observational study on 39 patients who underwent EBUS under general anesthesia was performed. Airways were managed with i-gel O2 by anesthesiologists unfamiliar with it. Data collected included patient characteristics, i-gel O2 positioning, mechanical ventilation, procedure, and complications occurring during and after the EBUS. Results: The i-gel airway was successfully positioned during the first attempt in 34/39 cases (87.2%). No failed positioning was recorded. The EBUS scope easily passed through the i-gel in all patients and in 14 (35.6%) cases it was also inserted through the esophagus allowing the examination or fine needle aspiration of paraesophageal lymph nodes. In one case, during the EBUS procedure, the i-gel was dislocated but easily put in place again. During EBUS, air leakages were significant in 2 cases (5.1%) and minimal in 14 cases (35.9%). A brief self-solved laryngospasm and a bronchospasm during bronchoscopy were recorded. After recovery, no patients had dysphagia; mild odynophagia and pharyngodinia were referred by 2 (5.1%) and 12 (30.1%) patients, respectively. Conclusions: The i-gel O2 airway is easy to position and manage even for anesthesiologists unfamiliar with it. This supraglottic airway device is suitable for a complete endosonographic evaluation of the mediastinum.","PeriodicalId":23450,"journal":{"name":"Tumori Journal","volume":"23 1","pages":"86 - 90"},"PeriodicalIF":0.0,"publicationDate":"2019-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82428258","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Atypical epithelial proliferations such as atypical lobular hyperplasia, lobular carcinoma in situ, and ductal carcinoma in situ may accompany areas of sclerosing adenosis. We present a case of ductal carcinoma in situ and sclerosing adenosis with metastatic carcinoma on sentinel lymph node. Case description: A 40-year-old woman presented with a palpable mass in her left breast. Radiologic studies showed a lesion suggesting malignancy in the left breast and atypical lymph node in the left axillary region. Left lumpectomy and sentinel lymph node biopsy was performed. Histopathologic examination revealed lobulocentric lesions with glandular proliferation and hyalinizing stroma in between. Foci of high-grade cribriform and solid type ductal carcinoma in situ were observed. Sentinel lymph node biopsy showed micrometastasis in one lymph node section. Based on these findings, the patient was diagnosed with high-grade ductal carcinoma in situ with sclerosing adenosis. However, the presence of micrometastasis in the lymph node suggested occult invasion that we were not able to detect. Conclusion: Ductal carcinoma in situ with sclerosing adenosis can mimic invasive carcinoma both radiologically and histologically. It should be kept in mind that there may be occult invasive carcinoma in patients with ductal carcinoma in situ whether the lesion is accompanied by sclerosing adenosis or not. Multiple sections and immunohistochemical studies can be of help.","PeriodicalId":23450,"journal":{"name":"Tumori Journal","volume":"56 1","pages":"NP63 - NP66"},"PeriodicalIF":0.0,"publicationDate":"2019-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77062313","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nivolumab, an immune checkpoint inhibitor directed against programmed death-1, has been approved for non-small cell lung cancer (NSCLC) in pretreated patients. Although it is generally well-tolerated, immunotherapy may be complicated by a wide range of immune-mediated adverse events. We describe the case of an uncommon skin toxicity arising as alopecia universalis induced by nivolumab in a patient with NSCLC. Case description: A 58-year-old man received nivolumab for metastatic NSCLC after progression to 3 lines of chemotherapy. The treatment was prescribed in June 2016, and induced a rapid and significant disease response. Nivolumab was well-tolerated until May 2017, when partial alopecia at hair and eyelashes appeared. In the next months, alopecia became complete and extended to the whole body surface. The dermatologic picture was compatible with alopecia areata. A topical steroid therapy was attempted, without benefit. The patient refused systemic treatments and is still undergoing nivolumab without new toxicities and with persistent disease response. Conclusions: This case suggests that alopecia areata may be a rare immune-related adverse event of immune checkpoint agents. Its late onset in our patient is uncommon and unexpected, underlining that the risk of nivolumab-induced toxicity is not limited to the beginning of treatment. Despite its rarity, alopecia areata should be considered in the range of adverse events potentially induced by immune checkpoint inhibitors even in the long term. Potential association between toxicity and efficacy of immunotherapy in NSCLC warrants further investigation.","PeriodicalId":23450,"journal":{"name":"Tumori Journal","volume":"17 1","pages":"NP57 - NP62"},"PeriodicalIF":0.0,"publicationDate":"2019-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85257130","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Door-to-door time was broken down into different steps, which were crucial to RT session. Results: A total of 594 treatment fractions were monitored. Median treatment time was 22.4 minutes (17.2–30.8) for PMRT and 14.4 minutes (10.9–23.5) for WBRT-SIB. The mean beam-on time accounted for 61.36% of the overall treatment time for PMRT compared to 57% for WBRT-SIB. The beam-on time was a much more time-consuming process.
