PIK3CA inhibitor therapy is approved for patients with advanced HR+/HER2- endocrine-resistant BC with somatic PIK3CA mutations. Such targeted therapy improved patient disease-free survival. Method: Analyses of PIK3CA gene mutations were performed in five University Hospital Centers in Croatia. Qualitative detection of PIK3CA gene mutations was performed on DNA extracted from 507 breast cancer samples, by the real-time PCR method using Cobas® PIK3CA mutation test. Results: PIK3CA gene mutations were detected in 209 (42.2%) out of 495 successfully analyzed cases. In 12 cases (2.4%), the tumor tissue was not of sufficient quality for analysis. Most mutations were detected in the helical (41.2%) and kinase domains (46.9%) of the PIK3CA protein. The most frequently detected mutations were H1047L/R/Y (46.4%), E545A/D/G/K (26.3%) and E542K (13.9%), followed by N345K (8.1%). PIK3CA mutations were detected in 44.8% of primary BC cases and in 39.6% of metastatic lesions (χ2=0.647; P=0.421). The age of the tissue did not significantly affect the percentage of detected mutations (χ2=0.543; P =0.461). Institutions differed in the number of analyzed cases, but not in the percentage of detected PIK3CA mutations (χ2=6.23; df=4; P=0.183) nor in the frequency of the most common mutations (χ2=2.65; df=4; P=0.618). Conclusion: The frequencies of PIK3CA mutations correspond to those reported in the literature. We have shown that the tissue of primary BC as well as metastatic lesions are suitable for analysis, and that the age of the tissue is not a significant obstacle in the analysis.","PeriodicalId":53700,"journal":{"name":"Libri Oncologici","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41333247","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 main goal is to preserve the mobility of the tongue, which allows the restauration of mastication, deglutition, and articulation. Today, a standard method for reconstruction of floor of the mouth defects is free microvascular flaps, especially radial forearm free flap. Despite that, a potential problem is the high perioperative risk and high complication rate associated with the patient’s age and comorbidities. Current literature suggests that a local nasolabial flap is a reliable treatment option for reconstruction of this type of defect, with a low complication rate and excellent functional and aesthetic results. The aim of this case presentation is to show the use of a local nasolabial flap for reconstruction of the floor of the mouth and to determine the criteria for this type of reconstruction. We present a patient who underwent resection of a floor of the mouth tumor. Due to the patient’s age, medical condition, and comorbidities, the defect was reconstructed with a local nasolabial flap. There were no postoperative complications. Articulation, mastication, and deglutition were satisfactorily rehabilitated. Follow-up showed no signs of recurrent disease twelve months postoperatively. To conclude, a local nasolabial flap is still an important reconstructive choice for oral cavity defects, especially for elderly patients with multiple comorbidities who have a higher risk of perioperative complications.","PeriodicalId":53700,"journal":{"name":"Libri Oncologici","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43514152","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}

Methods: The data were collected retrospectively from the medical history of 15 patients. They included the patient’s age at diagnosis, family history of malignancies, histological subtype, grade, breast cancer immunophenotype, stage of disease, status and types of BRCA mutations, type of surgical and oncological treatment, the specifics of metachronous bilateral breast cancers, the specifics of synchronous breast and ovarian cancers, and the outcome of treatment through overall survival (OS). Results: The median age of patients at the time of diagnosis of breast cancer was 53 years, and for ovarian cancer it was 56 years. A positive family history was confirmed in 13 patients (87%). All ovarian cancer patients had a high-grade serous histologic type, most often diagnosed in FIGO stages III and IV. Breast cancers were most commonly diagnosed in stages IA and IIA, with equally represented triple-negative and luminal immunophenotypes. The most common mutation was BRCA1 c.5266dup.

Our case report is about a 59-year-old patient which was presented with bilateral inguinal lymphadenitis, scrotal and penile edema. A biopsy of the change in the penis confirmed squamous cell carcinoma. Partial amputation of the penis and an excisional biopsy of the inguinal lymph nodes was performed, which confirmed the metastasis to the lymph nodes. Diagnostic imaging revealed bilateral enlarged inguinal lymph nodes which were later surgically removed. Postoperative CT scan showed three suspected lung metastases. The patient was then treated with polychemotherapy. Follow-up CT scan showed complete regression of metastatic changes in the lungs but also showed local recurrence in the area of the penile root. Radiotherapy with concomitant administration of cisplatin was conducted. Penile cancer is an aggressive disease that can be cured at an early stage if adequate treatment is applied. We highlight the importance of a multimodal and multidisciplinary approach consisting of polychemotherapy, surgical treatment, and radiotherapy.","PeriodicalId":53700,"journal":{"name":"Libri Oncologici","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47654631","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}

We investigated the relationship between indirect hematological parameters, neutrophil-to lymphocyte ratio – NLR, plateletsto-lymphocyte ratio – PLR, systemic immune-inflammation index – SII and the treatment outcome. Additionally, we also followed the overall survival (OS) rate. The obtained results report assessed parameters before and after surgical intervention. Of importance is to emphasize that at a cut-off value of 2.65 (P = 0.001) and 3.30 (P < 0.001), a decline in the NLR value was noticed after surgical removal of the breast cancer. The same decrease was observed for SII after surgery (P < 0.001). Through the study, SII has been shown to be a more relevant parameter compared to NLR and PLR. The study outcome recommends the cut-off value of 2.65 as the optimal for NLR in predicting the effectiveness and successfulness of the surgical procedure.","PeriodicalId":53700,"journal":{"name":"Libri Oncologici","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41535687","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}

Incidence of this carcinoma is increasing at a great rate. Disease often manifests asymptomatically and to make the final diagnosis is often challenging. Screening of patients at risk is based on ultrasound (US) examinations, which in the setting of suspicion lesion findings often converts to multiphasic computed tomography (CT) and magnetic resonance imaging (MRI) procedures for advanced disease evaluation. The selection of treatment modality depends on tumor size and location, extrahepatic spread and subsequent liver disease. For years the first line of treatment was liver resection and transplantation. Locoregional therapy is a novel approach to diverse stages of HCC with good response and higher overall survival rates, especially in early stages. Transarterial chemoembolization (TACE) is the method of choice in patients with multifocal HCC and maintained liver function, unsuitable for surgical treatment. We present a patient with HCC in the setting of hepatitis C virus (HCV) infection, treated with combined methods of locoregional therapy.","PeriodicalId":53700,"journal":{"name":"Libri Oncologici","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43624450","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}
