The etiology and p...Androgenic alopecia, also known as seborrheic alopecia, is the most common hair loss disorder in dermatology clinics, mainly characterized by hair follicle miniaturization and progressive hair loss. The etiology and pathogenesis of androgenic alopecia are not clear, but may be related to heredity and androgen metabolism. Currently, minoxidil and finasteride are the only two drugs approved by the U.S. Food and Drug Administration (FDA) for AGA treatment, other treatments include oral minoxidil, hair transplantation, low energy laser therapy (LLLT), platelet-rich plasma (PRP), Chinese medicine microneedles, and combination therapy. With the development of medicine and science, we have ushered in the era of biologics and targeted therapy. In recent years, a variety of signaling pathways for androgenic alopecia have been found, which may provide a basis for targeted therapy for androgenic alopecia.展开更多

Nowadays, considering the increasing mean lifespan of populations in developed countries, the disease is becoming more and more a health concern, and the search for an effective cure has turned into＂a real need＂.展开更多

Restaging CT and PET scans revealed massive involvement of the liver. She was treated with a combination of gene targeted and cytotoxic chemotherapy including capecitabine, erlotinib, bevacizumab and phenylbutyrate. She tested weakly positive for HER-2 despite prior negative FISH, which prompted us to add trastuzumab to her regimen. Baseline CT revealed five liver tumors—the sum of the products of the two largest perpendicular diameters was 110 cm2. Follow-up CT after three months of treatment revealed 62% decrease in total tumor load. More than 50% decrease in tumor size persisted on two follow-up CT scans, confirming partial response. She developed progressive disease after 15 months of treatment. A group of 16 women, including this patient, diagnosed with triple negative breast cancer with distant metastases were treated by our team with a combination of gene targeted therapy and chemotherapy. Six percent of patients obtained partial response, 25% minor response, 31% stable disease, and 38% progressive disease. The median duration of treatment in patients who relapsed after the second-, third- and fourth- to seventh-lines of chemotherapy was 59 weeks, 22 weeks and 17 weeks, respectively. Comparison of results obtained with cytotoxic chemotherapy revealed that MDT in the second- and third-lines was only nine and four weeks, respectively. In conclusion, this case report indicates that it is possible to obtain durable objective response of recurrent TNBC with a combination of gene targeted agents.展开更多

The prognosis for GBM remains poor with a five-year survival rate between 1% and 2%. The prospects for patients with recurrent GBM (RGBM) are much worse, with the majority dying within 6 months. This publication provides a brief description of the treatment of 11 GBM patients treated with sodium phenylbutyrate (PB) in combination with pazopanib, m-TOR inhibitors, and other agents. The treatment was associated with tolerable side effects and resulted in objective responses in 54.5% of cases (complete response 18.2%, partial response 36.3%) and 27.3% cases of stable disease. The preferable treatment regimen consisted of PB, pazopanib, dasatinib, everolimus, and bevacizumab (BVZ). For various reasons not all patients were compliant with the treatment regimen. In patients who strictly complied with the treatment plan, all responded as CR or PR. Based on preliminary findings, the authors propose further phase I/II clinical trials with PB in combination with pazopanib, dasatinib, everolimus, and BVZ in patients with RGBM who failed standard surgery, radiation therapy and chemotherapy. With proper dose reductions, the treatment appears to be well-tolerated. Molecular profiling of patient subgroups with favorable genomic signatures may help to select patients for future studies.展开更多
