Since the nose is the most prominent part in the face, the plastic surgeons are interested in the continued effort for rhinoplasty. Nasal tip projection is essential to optimal nasal for the patient's face. But, the nasal tips of Orientals are characterized by bulbous appearance due to thick and tense skin, flaring of nostril. and restriction of nasal tip projection due to underdevelopment of medial crus of alar cartilage and short columella. Most orientals want to correct their nasal tip as well as shape of nose. We present clinical cases of various nasal tip deformities which were corrected with various operative methods through either alar rim incision of open rhinoplasty incision depending upon the severity of tip deformity in order to achieve more natural tips and good nasal tip projection. And the clinical cases were categorized into causes of nasal tip deformity and methods of nasal tip augmentation. We are reporting these reporting these cases with review of literatures.

Squamous cell carcinoma of the ovary is rare. It is considered to be associated with benign cystic teratoma, Brenner tumor and ovarian endometriosis which undergo malignant degeneration in their epithelial layers. Although ovarian metastasis from advanced cervical cancer is well known, however, ovarian metastasis from microinvasive cervical cancer is extremely rare. Because there are few reports about squmaous cell carcinom of the ovary, the pathogenesis is still not well known. Recently we experienced a case of squamous cell carcinoma in ovary presenting 109 months after surgical therapy of a microinvasive cervical cancer. We report this case with a brief review of literature and possible pathogenesis.

Purpose: We aimed to assess the real-world efficacy of nab-paclitaxel in metastatic breast cancer patients. Materials and Methods: This is a retrospective study performed in two tertiary referral hospitals in Korea. Patients with metastatic breast cancer treated with nab-paclitaxel (Abraxane®) between March 2016 and March 2020 were enrolled. Results: A total of 102 patients with metastatic breast cancer were included. Patients were heavily pre-treated with a median of four prior lines of chemotherapy (5 lines when including endocrine therapy in hormone-receptor-positive patients), and 66 patients (64.7%) were exposed to taxanes in the metastatic setting. According to St. Gallen molecular subtypes, 36 patients (35.3%) were luminal A, 28 (27.5%) were luminal B, 18 (17.7%) were human epidermal growth factor receptor 2–positive and 20 (19.6%) had triple-negative disease. Fifty patients (49.0%) were treated with a 3-weekly regimen (260 mg/m2 on day 1 every 3 weeks), and 52 (51.0%) were treated with a weekly regimen (100 mg/m2 every week). Objective response rate was 22.9%. After a median follow-up of 22.0 months, median progression-free survival (PFS) was 4.0 months (95% confidence interval [CI], 2.6 to 4.8) and median overall survival was 8.7 months (95% CI, 7.5 to 11.2). Patients treated with weekly regimen had longer PFS compared to 3-weekly regimen (5.5 vs. 2.3 months, p < 0.001). Multivariate analysis revealed the treatment regimen as an independent prognostic factor for PFS. There was no grade 3 or 4 hypersensitivity reaction. Conclusion This real-world data shows that nab-paclitaxel is a reasonable treatment option in heavily pre-treated and/or taxane-exposed metastatic breast cancer patients.

PURPOSE: With the emergence of next-generation sequencing (NGS) technology, profiling a wide range of genomic alterations has become a possibility resulting in improved implementation of targeted cancer therapy. In Asian populations, the prevalence and spectrum of clinically actionable genetic alterations has not yet been determined because of a lack of studies examining high-throughput cancer genomic data. MATERIALS AND METHODS: To address this issue, 1,071 tumor samples were collected from five major cancer institutes in Korea and analyzed using targeted NGS at a centralized laboratory. Samples were either fresh frozen or formalin-fixed, paraffin embedded (FFPE) and the quality and yield of extracted genomic DNA was assessed. In order to estimate the effect of sample condition on the quality of sequencing results, tissue preparation method, specimen type (resected or biopsied) and tissue storage time were compared. RESULTS: We detected 7,360 non-synonymous point mutations, 1,164 small insertions and deletions, 3,173 copy number alterations, and 462 structural variants. Fifty-four percent of tumors had one or more clinically relevant genetic mutation. The distribution of actionable variants was variable among different genes. Fresh frozen tissues, surgically resected specimens, and recently obtained specimens generated superior sequencing results over FFPE tissues, biopsied specimens, and tissues with long storage duration. CONCLUSION: In order to overcome, challenges involved in bringing NGS testing into routine clinical use, a centralized laboratory model was designed that could improve the NGS workflows, provide appropriate turnaround times and control costs with goal of enabling precision medicine.
