Targeted Removal of Axillary Lymph Nodes After Carbon Marking in Patients with Breast Cancer Treated with Primary Chemotherapy

In breast cancer patients who have received primary chemotherapy and then no longer have any suspicious lymph nodes clinically and/or on imaging, marking of initially suspicious axillary lymph nodes with targeted removal has recently been discussed and practised both in Germany and internationally as an alternative to complete axillary lymph node dissection. Tattooing of the suspicious lymph nodes with a highly purified carbon suspension is currently being investigated in clinical studies. Compared with other techniques, the advantages of this method are the high rate of intraoperative lymph node detection, avoidance of an immediately preoperative localisation procedure and the low costs. The practical aspects of lymph node tattooing and the current data regarding this method will be described.

Real-World Study of Cisplatin, Etoposide, and Bleomycin Chemotherapy Regimen in Gestational Trophoblastic Neoplasia

Objective. Little observational data exist regarding the use of cisplatin, etoposide, and bleomycin (BEP) chemotherapy regimen in patients with gestational trophoblastic neoplasia (GTN). Methods. This is a retrospective study of 95 patients with GTN in our center from June/2010 to June/2018. All patients received at least 2 cycles of BEP chemotherapy. The primary outcomes were the rate of complete remission (CR) and overall survival (OS). The secondary outcomes were disease-free survival (DFS), pregnancy rates after BEP exposure, drug resistance rate, and other adverse events. Results. Of the 95 patients included, 66 (69.5%) patients received BEP as primary treatment and 29 (30.5%) were Salvage chemotherapy. The median age at diagnosis was 37 years (range 29.75-46) and 34 years (range 27-40) in two groups, respectively. The median WHO prognostic scores were 6 (range 3.5-8), and 77.32% of patients were FIGO stage III-IV in the primary treatment group. The median WHO prognostic scores were 5 (range 3-9), and 66.55% of patients were FIGO stage III-IV in the salvage treatment group. Median cycles of BEP treatment were 4 (3, 5) and 3 (2, 4) in two groups, respectively. In the primary chemotherapy group, 18.2% received additional hysterectomy, 4.5% received UAE for vaginal bleeding, and 1.52% received whole-brain radiotherapy. In the salvage chemotherapy group, 20.7% received hysterectomy, 6.9% received lobectomy, 3.4% received hysteroscopic lesion resection, and 3.4% received whole-brain radiotherapy. CR rates to initial chemotherapy were 86.4%, including 87.9% in the primary chemotherapy group and 82.8% in the salvage chemotherapy group. No predictive factor of chemotherapy resistance was identified. The rate of 5 year-DFS was 96.52% (95% CI 86.78–99.12) in the primary chemotherapy group and 92.44% (95% CI 73.02-98.06) in the salvage chemotherapy group. The rate of 5 year-OS was 98.31% (95% CI 88.57–99.76) and 95.65% (95% CI 79.93-99.38) in the two groups, respectively. During the treatment, neutropenia, thrombocytopenia, anemia, and liver dysfunction occurred in 80.3%, 6.1%, 25.8%, and 50% primary chemotherapy patients and 82.8%, 31%, 10.3%, and 86.2% salvage chemotherapy patients. In patients with fertility requirements, live birth rates were 100% (10/10) in primary chemotherapy patients and 80% (4/5) in salvage chemotherapy patients. Conclusions. BEP regimen was effective in the treatment of GTINs. The treatment was well tolerated, with no safety concerns on patients’ fertility.

Primary Chemotherapy in a 47-Year-Old Patient with Giant Ulcerative and Necrotizing Nonseminomatous Testicular Germ Cell Tumor

Testicular cancer is a rare disease; however, cure rates are high for all tumor stages. Mostly, the disease is diagnosed in an early (local) stage. We report the case of a 47-year-old male patient with a giant nonseminomatous germ cell tumor. At the time of diagnosis, the patient demonstrated a necrotizing and ulcerating growing mass in the left scrotum with an approximate size of 22 × 18 cm. According to the prognostic classification of the International Germ Cell Cancer Collaborative Group (IGCCCG 1997), the patient exhibited a high-risk profile due to alpha-fetoprotein >10,000 ng/mL and lactate dehydrogenase >10× the upper limit of normal in serum. Primary orchiectomy was infeasible due to the tumor’s size, the patient’s poor general condition and initial intensive care unit treatment. Primary systemic chemotherapy was applied. After 3 cycles of cisplatin, etoposide and bleomycin, along with 1 cycle of cisplatin, etoposide and ifosfamide, tumor resection with histomorphological examination showed a complete pathological response. Despite the delayed initiation of the therapy, primary chemotherapy was completed timely and showed promising results. Reasons for the late hospitalization were personal responsibilities regarding his family. Better awareness and knowledge of testicular cancer among young men might prevent the here reported delay of medical consultation and avoid testicular tumors of such enormous size. Psychosocial assessment and distress management is important as an integral part of comprehensive care of testicular cancer patients.

Chemotherapy-induced myasthenic crisis in thymoma treated with primary chemotherapy with curative intent on mechanical ventilation: a case report and review of the literature

Background Thymoma is an uncommon cancer often associated with myasthenia gravis, an autoimmune disorder of the neuromuscular junction characterized by muscular fatigability. In patients with advanced nonmetastatic thymoma, primary chemotherapy may be required to induce tumor shrinkage and to achieve radical resection. Cancer chemotherapy has been anecdotally reported as a trigger factor for worsening of myasthenia gravis in thymic epithelial cancers. The study of uncommon cases of chemotherapy-related myasthenic crisis is warranted to gain knowledge of clinical situations requiring intensive care support in the case of life-threatening respiratory failure. Case presentation We report a case of an 18-year-old Caucasian woman with advanced Masaoka-Koga stage III type B2 thymoma and myasthenia gravis on treatment with pyridostigmine, steroids and intravenous immunoglobulins, who developed a myasthenic crisis 2 hours after initiation of cyclophosphamide/doxorubicin/cisplatin primary chemotherapy. Because of severe acute respiratory failure, emergency tracheal intubation, mechanical ventilation, and temporary (2 hours) discontinuation of chemotherapy were needed. Considering the curative intent of the multimodal therapeutic program, we elected to resume primary chemotherapy administration while the patient remained on mechanical ventilation. After 24 hours, the recovery of adequate respiratory function allowed successful weaning from respiratory support, and no further adverse events occurred. After 3 weeks, upon plasma exchange initiation with amelioration of myasthenic symptoms, a second course of chemotherapy was given, and in week 6, having documented partial tumor remission, the patient underwent radical surgery (R0) and then consolidation radiation therapy with 50.4 Gy in 28 fractions in weeks 15–20. Conclusions This case report, together with the only four available in a review of the literature, highlights that chemotherapy may carry the risk of myasthenic crisis in patients affected by thymoma and myasthenia gravis. To our knowledge, this is the first reported case of chemotherapy continuation on mechanical ventilation in a patient with chemotherapy-induced myasthenic crisis requiring tracheal intubation. The lesson learned from the present case is that, in selected cases of advanced thymoma, the paradoxical worsening of myasthenia gravis during chemotherapy should not be considered an absolute contraindication for the continuation of primary chemotherapy with curative intent.
