Selpercatinib plus cemiplimab in RET positive medullary thyroid cancer patient with skin cancers
No full textBackground: Remarkable advancements in the therapeutic armamentarium for medullary thyroid cancer (MTC) have been observed in the last 10 years. The current understanding of driver mutations, such as RET and RAS, has enabled the development of new therapies for advanced and metastatic disease, demonstrating improved efficacy. Patient Findings: A patient with RET-positive hereditary MTC developed multiple skin cancers (basal cell and squamous cell carcinomas) along with progression of MTC after 12 years of treatment with vandetanib. Once surgery to manage skin cancers has been excluded, the patient received a combination of selpercatinib and cemiplimab, and has been on this treatment at the full dose for 15 months, with ongoing therapy. Summary: The combination of selpercatinib and cemiplimab was possible, with no new safety signals observed
Carbon ion radiotherapy in gynaecological oncology: where we are and where we are headed
No full textPurpose: In the present brief report, the authors summarized the data on the use of carbon ion radiotherapy in gynaecological malignancies starting from the preclinical evidence to move forward the clinically available literature and hence focusing on the possible future application directions. Methods: This is a short report of the published studies on the role of carbon ion radiotherapy in the treatment of gynaecological malignancies. Results: The use of carbon ion radiotherapy in rare and radioresistant gynaecological tumors is supported by preclinical and clinical data. In particular, carbon ion radiotherapy appears to be safe and effective in the management of cervical adenocarcinomas, unresectable endometrial cancers, mucosal melanomas of the lower genital tract and vulvar adenoid cystic carcinomas. Moreover, considering the dosimetric characteristics, carbon ions are suitable for recurrent disease in the pelvis. Prospective and phase II trials on gynaecological melanomas and pelvic relapses after radiotherapy are currently ongoing. The future study directions might be the oligometastatic diseases and the oncofertility. Conclusions: More and more growing preclinical and clinical evidence supports the use of carbon ion radiotherapy in gynaecological oncology. Strong and multidisciplinary collaborations at national and international levels are desirable to better understand the therapeutic and organizational benefits of this new technology
A small bowel adenocarcinoma harboring a DDR2 mutation in a celiac patient
No full textWe present the case of a 62-year-old man with a history of celiac disease and IgA deficiency, following a strict gluten-free diet that was admitted to our hospital for recurrent abdominal pain, fatigue and melena. Esophagogastroduodenoscopy and colonoscopy with biopsies were normal. A video-capsule endoscopy was performed and revealed a sub-stenosing, vegetating, and bleeding lesion in the first jejunal loop. He underwent laparotomic surgery with resection of the involved segment with loco-regional lymphadenectomy. The pathological report described a poorly differentiated adenocarcinoma of the jejunum, stage IIIA (pT3pN1). Analysis of next-generation sequencing (NGS) of DNA on the surgical sample revealed a likely pathogenetic variant in exon 15 of the DDR2 gene (c.2003G > A) and a TP53 non-frame-shift deletion (c.585_602del). Considering the risk of recurrence, he was candidate to 6 months of adjuvant chemotherapy with platinum salt and fluoropyrimidine. Thirty-eight months after the diagnosis, the patient is still disease free and in good clinical condition. This is the first described case of SBA with DDR2 mutation. Considering the limited therapeutic options beyond surgery for SBA, molecular analyses could become promising for the search for potential targetable alterations for treatments with new available drugs
Adenoid Cystic carcinoma of minor salivary glands (AdCCmSG): a multidisciplinary update
No full textIntroductionAdenoid cystic carcinoma of minor salivary glands (AdCCmSG) represents a 'rarity in the rarity,' posing a clinical challenge in lack of standardized, evidence-based recommendations. At present, AdCCmSG management is mostly translated from major salivary gland cancers (MSGCs). Ideally, AdCCmSG diagnostic-therapeutic workup should be discussed and carried out within a multidisciplinary, high-expertise setting, including pathologists, surgeons, radiation oncologists and medical oncologists.Areas CoveredThe present review provides an overview of epidemiology and pathologic classification. Moreover, the most recent, clinically relevant updates in the treatment of AdCCmSG (Pubmed searches, specific guidelines) are critically discussed, aiming to a better understanding of this rare pathologic entity, potentially optimizing the care process, and offering a starting point for reflection on future therapeutic developments.Expert OpinionThe management of rare cancers is often hindered by limited data and clinical trials, lack of evidence-based guidelines, and hardly represented disease heterogeneity, which cannot be successfully tackled with a 'one-size-fits-all' approach. Our goal is to address these potential pitfalls, providing an easy-to-use, updated, multidisciplinary collection of expert opinions concerning AdCCmSG management as of today's clinical practice. We will also cover the most promising future perspectives, based on the potential therapeutic targets highlighted within AdCCmSG's molecular background
Vitamin B12 status in hospitalised cancer patients: Prevalence and clinical implications of depletion and hypervitaminosis
No full textBackground & aims: The prevalence and clinical significance of vitamin B12 alterations in patients with cancer are poorly understood. We aimed to assess the prevalence and risk factors of vitamin B12 depletion or hypervitaminosis in patients with cancer. Methods: We retrospectively included hospitalised patients with cancer in 2017-2022. Plasma B12 levels were stratified as very low (VL, 813 pg/ml). We collected demographic and several clinical data (e.g., comorbidities, nutritional status, ECOG-PS, cancer site and stage). Univariate and multivariate analyses for factors associated to the vitamin B12 status were fitted. Results: 788 patients (F/M ratio 1.05, median age 72 years, [25th, 75th percentiles 62, 78 years]) were included. Vitamin B12 was VL in 14.1%, L in 19.4%, N in 49.4%, and H in 17.1% cases. Vitamin B12 distribution increased significantly as function of ECOG-PS levels. Patients with breast cancer were characterized by the highest median B12 value, while colorectal cancer patients by the lowest. Vitamin B12 was also significantly higher in advanced compared to early-stage patients as well as in those who had liver failure. Multivariate analysis showed that the probability of H vs. VL B12 levels was significantly increased in patients with hypoproteinemia, hypo-prealbuminemia, and ECOG-PS>2, and decreased in those with colorectal and gastric cancer. Conclusion: Vitamin B12 impairment is common in cancer patients. Increased vitamin B12 is associated with an impaired clinical status, while vitamin B12 depletion is more common in early-stage cancer and in elderly patients. (c) 2024 The Author(s).

Thrombotic Events during Lenvatinib Treatment: A Single Institution Experience
No full textLenvatinib is the standard treatment for radioiodine-refractory differentiated thyroid cancer (RR-DTC). Thromboembolic (TE) side effects are quite rare (1–3% of treated patients) in clinical trials. Nevertheless, patients with predisposing factors are at a higher risk of developing cardiovascular adverse events. Reduction of lenvatinib starting dose and cardiologic counselling to provide appropriate supportive therapies are usually recommended for high-risk patients. From 2016 to 2022, we analyzed a series of 16 patients who were consecutively treated at our institution. All except one patient received a reduction in their dosage after two cycles of therapy because of toxicities, and four patients (25%) suffered from TE. The observed incidence in our patient sample seemed to be higher than expected. We hypothesized that our patient sample might be at higher risk probably because of the heavy prior loco-regional treatments performed
Rare Head and Neck Cancers and Pathological Diagnosis Challenges: A Comprehensive Literature Review
No full textHead and neck cancers (HNCs) arise from anatomically adjacent sites and subsites, with varying etiological factors, diagnostic strategies, prognoses, and treatment approaches. While conventional squamous cell carcinoma (SCC) is the most common histology in the head and neck district, HNCs encompass a variety of rare histopathological entities, categorized into epithelial tumors such as salivary gland cancers, sinonasal tumors, neuroendocrine tumors, malignant odontogenic tumors, and SCC variants versus non-epithelial tumors including soft tissue sarcomas, mucosal melanomas, and hematological malignancies. Rare HNCs (R-HNCs) represent a diagnostic and clinical challenge, requiring histopathological expertise, the availability of peculiar molecular analysis, and the personalization of local and systemic treatments, all guided by a multidisciplinary tumor board. Here, we provide a comprehensive literature review on R-HNCs, emphasizing key histopathological and molecular characteristics that are crucial for guiding treatment decisions. An insight about the latest developments in systemic treatments is also reported
Management of loco-regionally advanced squamous laryngeal cancer in elderly patients
No full textPurpose: To describe the management and outcomes of loco-regionally advanced (stages III-IV) laryngeal cancer (LRALC) in elderly patients.
Methods: Clinical records of 88 LRALC patients treated at our Institution from 2002 to 2017 were retrospectively reviewed. Patients were divided in 2 subgroups: age > 65 years (elderly) and age ≤ 65 years (controls). Survivals were estimated with Kaplan-Meier method and compared with log-rank test, multivariate analysis were performed with Cox proportional hazard methods.
Results: Eighty-eight LRALC patients were included: 45 elderly and 43 controls. Median follow-up was 55.3 months. Median age was 66 years (range 41-84) in the overall population, 72 years (range 66-84) in the elderly cohort. The majority (98%) of elderly patients had at least one comorbidity (ACE27 1-3), while ACE27 was 0 in 37% of controls (p = 0.0001). ECOG PS was 0 in 42% of elderly vs 79% of controls (p = 0.0029). Clinical stage (TNM eighth edition) was III in 67%, IVA in 22% and IVB in 11%. Treatment consisted in total laryngectomy (TL) in 55%, chemo-radiation in 29%, exclusive radiotherapy in 9%, and conservative surgery in 7%. In elderly patients 2-year disease-free and overall survivals were 58% and 74%, respectively. Multivariate analysis performed on the overall group of 88 patients showed that age (HR 1.07, p = 0.0006) and TNM (for both 7th and 8th Editions HR 0.27 for stage III vs IV, p = 0.0005) maintained an independent statistical significant association with OS.
Conclusions: In this monocentric cohort, age and TNM confirmed their independent prognostic role in LRALC patients. Organ-preservation is still an unmet need in a significant portion of elderly patients
Use of lenvatinib in the treatment of radioiodine-refractory differentiated thyroid cancer: a multidisciplinary perspective for daily practice
No full textBackground: Most thyroid cancers of follicular origin have a favorable outcome. Only a small percentage of patients will develop metastatic disease, some of which will become radioiodine refractory (RAI-R). Important challenges to ensure the best therapeutic outcomes include proper, timely, and appropriate diagnosis; decisions on local, systemic treatments; management of side effects of therapies; and a good relationship between the specialist, patients, and caregivers.
Methods: With the aim of providing suggestions that can be useful in ev eryday practice, a multidisciplinary group of experts organized the following document, based on their shared clinical experience with patients with RAI-R differentiat ed thyroid cancer (DTC) undergoing treatment with lenvatinib. The main areas covered are patient selection, initiation of therapy, follow-up, and management of adverse events.
Conclusions: It is essential to provide guidance for the management of RAI-R DTC patients with systemic therapies, and especially lenvatinib, since compliance and adherence to treatment are fundamental to achieve the best outcomes. Whil e the therapeutic landscape in RAI-R DTC is evolving, with new targeted therapies, immunotherapy, etc., lenvatinib is expected to remain a first-line treatment and mainstay of therapy for several years in the vast majority of patients and settings. The guidance herein covers baseline work-up and initiation of systemic therapy, relevance of symptoms, multidisciplinary assessment, and patient education. Practical information based on expert experience is also given for the starting dose of lenvatinib, follow-up and monitoring, as well as the management of adverse events and discontinuation and reinitiating of therapy. The importance of patient engagement is also stressed
