Purpose: Epidermal growth factor receptor (EGFR) T790M mutation serves as an important predictor of osimertinib efficacy. However, little is known about how it works among patients with various timings of T790M emergence and treatment. Materials and Methods: Advanced EGFR-mutant lung adenocarcinoma patients with positive T790M mutation in tumor were retrospectively enrolled and observed to determine the outcomes of osimertinib treatment. We evaluated the association between patients' characteristics and the efficacy of osimertinib treatment, particularly with respect to the timing of T790M emergence and osimertinib prescription...

Baqun Zhang, Min Zhang
A dynamic treatment regime is a sequence of decision rules, each corresponding to a decision point, that determine that next treatment based on each individual's own available characteristics and treatment history up to that point. We show that identifying the optimal dynamic treatment regime can be recast as a sequential optimization problem and propose a direct sequential optimization method to estimate the optimal treatment regimes. In particular, at each decision point, the optimization is equivalent to sequentially minimizing a weighted expected misclassification error...

Patients with germline DNA mismatch repair deficiency (dMMR) have an increased risk of gastric cancer. From our institutional database, we identified 12 patients with germline dMMR gastric cancer. Ten patients (83%) underwent surgical resection, with a 5-year overall survival rate of 88%. None of the three patients who received preoperative therapy and five patients with recurrent or metastatic disease experienced a significant response to 5-fluorouracil-based chemotherapy.

BACKGROUND: Sentinel lymph node (SLN) resection is imperative for breast cancer staging. Axillary reverse mapping (ARM) can preserve arm draining nodes and lymphatics during surgery. ARM is generally performed with isosulfan blue (ISB), restricting its use for concurrent SLN biopsy. Indocyanine green (ICG) could serve as an alternative to ISB for ARM procedures. METHODS: SLN mapping and biopsy was performed via periareolar injection of 99 technetium-sulfur colloid (99m TcSc, TSC)...

BACKGROUND: Major depressive disorder (MDD) is characterized by high relapse/recurrence rates. Predicting individual patients' relapse/recurrence risk has proven hard, possibly due to course heterogeneity among patients. This study aimed to (1) identify homogeneous data-driven subgroups with different patterns of relapse/recurrence and (2) identify associated predictors. METHODS: For a year, we collected weekly depressive symptom ratings in 213 primary care MDD patients...

Adam Maidman, Lan Wang
Motivated by the Medical Expenditure Panel Survey containing data from individuals' medical providers and employers across the United States, we propose a new semiparametric procedure for predicting whether a patient will incur high medical expenditure. Problems of the same nature arise in many other important applications where one would like to predict if a future response occurs at the upper (or lower) tail of the response distribution. The common practice is to artificially dichotomize the response variable and then apply an existing classification method such as binomial regression or a classification tree...

Uterus transplantation was firstly tested with animal trials sixty-five years ago. Despite several successful attempts in human subjects, the different procedures still lay at the experimental stage, in need of further studies and investigations before they can be considered as standard clinical practices. Uterus transplant cannot be regarded as a life-saving procedure, but rather a method to restore woman ability to procreate, when lost, thus improving her quality of life. Uterus transplant is a complex surgical procedure and presents significant health threats...

OBJECTIVE: Infections with Corynebacterium tuberculostearicum are very rare as in most of the cases its isolation is associated with tissue colonization rather than infection. CASE REPORT: An 80-year old female patient was sent to the consultation hour of thoracic surgery for evaluation of a symptomatic persistent unilateral pleural effusion of her right lung. The differential diagnosis included either the presence of a chronic pleural empyema or the presence of malignancy...
