Clinicopathologic Classification of Renal Cell Carcinoma in Patients ≤40 Years Old From Peru.

Introduction: There are scant data on renal cell carcinoma (RCC) from relatively younger patients in South America using contemporary classification.

Methods: Fifty-nine consecutively treated patients with RCC (≤40 years old) were assessed from the National Institute of Neoplastic Diseases in Peru from 2008 to 2020 (34 males; 25 females), age range of 13 to 40 years.

Results: Most common presenting symptoms were flank pain (n = 40), hematuria (n = 19), and weight loss (n = 12).

Prognostic factors for patients with newly diagnosed brain metastasis from breast cancer.

Aim: This retrospective study determined features associated with brain metastasis (BM) in women with breast cancer.

Patients & Methods: A total of 215 initially early breast cancer cases were included. We reviewed files and CT scan images of BM.

[Parametrial involvement in cervical cancer IB1 patients treated with radical hysterectomy in Peru].

Objectives: To assess the frequency and factors associated with parametrial involvement (PI) in patients with cervical cancer IB1 who underwent radical hysterectomy (RH) at the National Institute of Neoplastic Diseases in Peru.

Materials And Methods: Cross-sectional study of 214 patients with cervical cancer IB1 undergoing RH with pelvic lymphadenectomy between 2007 and 2012. The population was compared with and without clinicopathological variables associated with PI such as age, tumor size, depth of infi histological grade and pelvic lymph node involvement.

Association between mammographic features and response to neoadjuvant chemotherapy in locally advanced breast carcinoma.

Purpose: Mammography is the cornerstone of breast cancer (BC) evaluation. This report investigates whether breast density (BD) and mammographic features of the tumor can provide information on both BC susceptibility to chemotherapy and other clinicopathologic features of locally advanced BC (LA BC).

Materials And Methods: We evaluated mammography films and clinicopathological information of patients with LA BC who received neoadjuvant chemotherapy (NAC) followed by tumor resection at the Instituto Nacional de Enfermedades Neoplásicas (INEN) from 2000 to 2011.
