Tumor mutational burden (TMB) has recently been identified as a biomarker of response to immune checkpoint inhibitors in many cancers, including melanoma. Co-assessment of TMB with inflammatory markers and genetic mutations may better predict disease outcomes. The goal of this study was to evaluate the potential for TMB and somatic mutations in combination to predict the recurrence of disease in advanced melanoma. A retrospective review of 85 patients with stage III or IV melanoma whose tumors were analyzed by next-generation sequencing was conducted. Fisher's exact test was used to assess differences in TMB category by somatic mutation status as well as recurrence locations. Kaplan–Meier estimates and Cox-proportional regression model were used for survival analyses. The most frequently detected mutations were TERT (32.9%), CDKN2A (28.2%), KMT2 (25.9%), BRAF V600E (24.7%), and NRAS (24.7%). Patients with TMB-L + BRAFWT status were more likely to have a recurrence [hazard ratio (HR), 3.43; confidence interval (CI), 1.29–9.15; P = 0.01] compared to TMB-H + BRAF WT. Patients with TMB-L + NRASmut were more likely to have a recurrence (HR, 5.29; 95% CI, 1.44–19.45; P = 0.01) compared to TMB-H + NRAS WT. TMB-L tumors were associated with local (P = 0.029) and in-transit (P = 0.004) recurrences. Analysis of TMB alone may be insufficient in understanding the relationship between melanoma's molecular profile and the body's immune system. Classification into BRAFmut, NRASmut, and tumor mutational load groups may aid in identifying patients who are more likely to have disease recurrence in advanced melanoma.

How Many Nodes to Take? Lymph Node Ratio Below 1/3 Reduces Papillary Thyroid Cancer Nodal Recurrence

xlomafota13 shared this article with you from Inoreader

Introduction

Papillary thyroid carcinoma (PTC) accounts for the majority of thyroid malignancies; risk of PTC recurrence over a 30-year period is approximately 30%, of which 70% occur as nodal metastases. Patients with nodal disease who are treated with therapeutic dissection are at higher risk for recurrence, but optimal nodal yield has not been defined. We aim to determine variables predictive of nodal recurrence of PTC within the first 5 years of surgery, with a focus on lymph node ratio (LNR), to inform clinical decision-making.

Methods

Retrospective chart review identified 41 patients with nodal recurrence of PTC and 284 without nodal recurrence following thyroid surgery from 2000 to 2015. Cohorts were compared with regards to clinical history, surgical findings, and tumor characteristics.

Results

The fraction of the patients who underwent therapeutic central or lateral lymph node dissection was significantly higher in the nodal recurrence cohort. Maximum tumor size, presence of extrathyroidal extension, largest lymph node focus, LNR, postoperative thyroglobulin level, and administration of postoperative radioactive iodine were significantly increased in the PTC nodal recurrence group. LNR greater than 0.3 held the highest level of significance as a binary cutoff and captured the larger proportion of patients in the nodal recurrence cohort (68.3%).

Conclusion

This study demonstrates characteristics to help assess risk of nodal recurrence of PTC and suggests LNR of lower than 0.3 is optimal to reduce risk of recurrence. The next steps include cohort studies to validate findings and weight variable analysis to optimize the extent of surgical therapeutic dissection.

Survival of adult patients with solid cancer

xlomafota13 shared this article with you from Inoreader

Bull Cancer. 2022 Feb 26:S0007-4551(22)00068-6. doi: 10.1016/j.bulcan.2022.01.010. Online ahead of print.

ABSTRACT

INTRODUCTION: Population-based cancer survival is a major indicator of effectiveness of cancer management. This study is the first population-based study to estimate the net survival (NS) of adult cancer patients in Reunion Island, a French overseas department with distinctive epidemiological, cultural, and sociodemographic characteristics.

METHODS: All adult incident cases (n=23,055) of invasive solid tumors diagnosed between 1998 and 2014 and registered in the Reunion Island Cancer Registry were included in the study. The Pohar-Perme estimator was used to estimate 1-, 3-, 5-, and 10-year NS.

RESULTS: 5-year NS ranged from 7% (liver in women) to 97% (thyroid cancer in women) for cancers diagnosed between 2006 and 2014. For the most common cancers, the age-standardized 5-year NS of women was 81% for breast canc er, 58% for colorectal cancer and 62% for cervical cancer. For men, the age-standardized 5-year NS was 85% for prostate cancer, 12% for lung cancer, and 52% for colorectal cancer. Age-standardized 5-year NS increased slightly with the period of diagnosis (from 1998-2005 to 2006-2014) for prostate, breast, head and neck, lung, colorectal (women), and stomach (men) cancers, remained stable for colorectal (men) cancer, and decreased slightly for cervical and stomach (women) cancers.

DISCUSSION: Overall, NS was lower in Reunion Island than in mainland France. While the epidemiological, cultural, and sociodemographic characteristics of the Reunionese population likely explain some of the observed differences compared to mainland France, site-specific studies are needed to explore the different determinants of survival in Reunion Island.

Thyroid and Parathyroid Conditions: Hyperthyroidism

ABSTRACT

Hyperthyroidism is an excess in thyroid hormone production caused by such conditions as Graves disease, toxic multinodular goiter, and toxic adenoma. Overt hyperthyroidism is defined as a low or undetectable thyrotropin (TSH) level with elevated triiodothyronine (T3) or thyroxine (T4) values, whereas subclinical hyperthyroidism is defined as low or undetectable TSH with normal T3 and T4 levels. Symp toms of hyperthyroidism include nervousness, heat intolerance, weight loss, and fatigue. The long-term consequences of unmanaged or poorly managed hyperthyroidism include increased risk of all-cause mortality, cardiovascular events, atrial fibrillation, sexual dysfunction, and osteoporosis. Overt and subclinical hyperthyroidism can be managed effectively with antithyroid drugs (eg, propylthiouracil, methimazole) or with definitive therapies (eg, radioactive iodine ablation, thyroidectomy). Subclinical hyperthyroidism is not always treated, although close monitoring is needed to prevent disease complications or progression to overt hyperthyroidism. Treatment for subclinical hyperthyroidism is recommended for patients 65 years or older with TSH levels lower than 0.10 mIU/L. Treatment also is recommended for symptomatic patients or those with cardiac or osteoporotic risk factors. Thyroid storm is a life-threatening complication of unmanaged or inadequately managed hyperthyroidism that warrants urgent treatment in a hospital setting.
