Primary squamous cell carcinoma of thyroid gland-First case report from state Punjab, India.

Primary squamous cell carcinoma of the thyroid is a very rare thyroid malignancy. In addition, due to its presentation as a locally advanced disease with a high tendency to metastasize, it has a poor prognosis and outcome. We report a 60-year-old male patient with PSCC, which was confirmed by immunohistochemistry on biopsy. The patient was staged as T4N1M0 and was planned as per the multidisciplinary team approach. In sum, pathologic examination and IHC aid in distinguishing this lesion and help in differentiating it from other tumors of similar histology. Furthermore, it also aids in planning treatment.

Prognostic factor for recurrence in esophagus cancer patients who underwent surgery for curative intent: A single-institution analysis.

OBJECTIVE: The purpose of this study is to analyze predisposing factors for a higher risk of recurrence in esophageal cancer patient who underwent surgery for curative intent and to do survival analysis of prognostic factors. MATERIALS AND METHODS: Between February 2018 and March 2020, we retrospectively identified 28 cases staged T1b to T4a managed electively at our institute as per multidisciplinary management plan. Demographic, clinical, radiological, operative, histopathological parameters, upfront surgery done or not, type of preoperative, and adjuvant treatment used and whether neoadjuvant or adjuvant therapy was planned along with waiting time for surgery, were assessed as potential risk factors. End point of study was to find potential risk factors for recurrence and to do their subgroup survival analysis. RESULTS: The recurrence rate in our study was 25% with a mean follow-up of 24 months. The median time of recurrence was 8.5 months, all recurrence occurred within 1 year. Overall DFS at 2 years was 72%. On univariate analysis, following prognostic factors were associated with high risk of recurrence, male sex X2 (1) =4.42, p = 0.035; histology subtype of adenocarcinoma X2 (1) = 7.07, p = 0.008; margin positive X2 (1) =3.76, p = 0.05; presence of lymph vascular invasion (LVI) X2 (1) =7.88, p = 0.005; presence of perineural invasion (PNI) X2 (1) =5.97, p = 0.015; postoperative T size >4 cm X2 (1) =3.86, p = 0.049; and nodal positivity X2 (3) =13.47, p = 0.004. CONCLUSIONS: Male sex, adenocarcinoma histological subtype, positive resected margin, presence of LVI and PNI, postoperative T size >4 cm, and high postoperative nodal positivity and whether neoadjuvant versus adjuvant therapy given (on K. M analysis) were the identified predictors of recurrence which compromised DFS.
