Background: Adrenocortical carcinoma, a rare malignancy, has a poor prognosis, and the treatment modalities have not been well established. This study aimed to analyze the trend of treatment modalities and outcomes of patients with adrenocortical carcinoma.
Methods: We retrospectively analyzed 94 patients with adrenocortical carcinoma between January 1995 and June 2020 for distributions according to the American Joint Committee on Cancer (AJCC) 8th edition tumor-node-metastasis (TNM) staging, the yearly trend of demographic features, differences in multidisciplinary treatment, and prognostic outcomes. Multidisciplinary treatment included any combination of treatment including surgery, mitotane, chemotherapy or radiation.
Results: The mean age and tumor size were 48.9 years and 11.7 cm, respectively. Fifteen patients (16.0%) underwent surgery only, and 56 (59.6%) underwent surgery with additional multidisciplinary treatments. Initial curative treatment was performed in all patients with stage 1 (n=5), 33 patients with stage 2 (n=34, 97.1%), 12 patients with stage 3 (n=19, 63.2%), and 11 patients with stage 4 (n=36, 30.6%) (P<0.0001). Two patients (40.0%) with stage 1 presented recurrence. In stages 2, 3, and 4, 57.6%, 58.3%, and 90.9% of patients who received curative treatment had recurrences, respectively. The annual trend presented statistical differences in mitotane use that have been increasing recently (P<0.0001).
Conclusions: Overall distribution of adrenocortical carcinoma stage was similar throughout the years. Although the rate of mitotane use in the treatment of patients with Adrenocortical carcinoma has increased over time, recurrences were common even after multidisciplinary curative treatment in all stages. The treatment effect and prognostic outcomes presented no promising progression even with adjuvant chemotherapy and mitotane use in addition to surgical treatment. Adrenocortical carcinoma still presented an extremely poor prognosis, and further prospective studies are needed.

Background: Private-part skin diseases (PPSDs) can cause a patient's stigma, which may hinder the early diagnosis of these diseases. Artificial intelligence (AI) is an effective tool to improve the early diagnosis of PPSDs, especially in preventing the deterioration of skin tumors in private parts such as Paget disease. However, to our knowledge, there is currently no research on using AI to identify PPSDs due to the complex backgrounds of the lesion areas and the challenges in data collection.

Importance: Serial circulating tumor DNA (ctDNA) has emerged as a routine surveillance strategy for patients with resected colorectal cancer, but how serial ctDNA monitoring is associated with potential curative outcomes has not been formally assessed.
Objective: To examine whether there is a benefit of adding serial ctDNA assays to standard-of-care imaging surveillance for potential curative outcomes in patients with resected colorectal cancer.
Design, Setting, And Participants: In this single-center (City of Hope Comprehensive Cancer Center, Duarte, California), retrospective, case cohort study, patients with stage II to IV colorectal cancer underwent curative resection and were monitored with serial ctDNA assay and National Cancer Center Network (NCCN)-guided imaging surveillance from September 20, 2019, to April 3, 2024.

Background: In patients with breast cancer staged ypN1 after neoadjuvant chemotherapy (NAC), there is limited evidence-based guidance regarding exemption from axillary lymph node dissection (ALND).
Methods: This study analyzed ypN1 breast cancer patients post-NAC from the Surveillance, Epidemiology, and End Results databases. Patients were categorized into the breast-conserving surgery (BCS) group and the total mastectomy (TM) group, and further divided by the number of positive lymph nodes (LNs).

Antibody-drug conjugates (ADCs) represent a novel class of targeted anti-tumor medications that utilize the covalent linkage between monoclonal antibodies and cytotoxic agents. This unique mechanism combines the cytotoxic potency of drugs with the targeting specificity conferred by antigen recognition. However, it is essential to recognize that many ADCs still face challenges related to off-target toxicity akin to cytotoxic payloads, as well as targeted toxicity and other potential life-threatening adverse effects, such as treatment-induced interstitial lung injury.

Purpose: The rarity of breast mucinous carcinoma (BMC) makes it challenging to study the prognosis of this disease across diverse racial populations. This study aimed to leverage epidemiological data on immigrant populations to elucidate the prognostic differences in BMC patients from various racial/ethnic backgrounds. The goal was to help formulate more personalized clinical practice guidelines for the management of this rare malignancy.
