Pressure related complications such as abdominal wall hernias occur with relative frequency in patients on peritoneal dialysis. Less frequently, a transudative pleural effusion containing dialysate can develop. This phenomenon appears to be due to increased intra-abdominal pressure in the setting of congenital or acquired diaphragmatic defects. We report three cases of pleuroperitoneal leak that occurred within a nine-month period at our institution. We review the literature on this topic, and discuss management options. The pleural effusion resolved in one patient following drainage of the peritoneum and a switch to haemodialysis. One patient required emergency thoracocentesis. The third patient developed a complex effusion requiring surgical intervention. The three cases highlight the variability of this condition in terms of timing, symptoms and management. The diagnosis of a pleuroperitoneal leak is an important one as it is managed very differently to most transudative pleural effusions seen in this patient population. Surgical repair may be necessary in those patients who wish to resume peritoneal dialysis, or in those patients with complex effusions. Pleuroperitoneal leak should be considered in the differential diagnosis of a pleural effusion, particularly a right-sided effusion, in a patient on peritoneal dialysis.

Background: Ipilimumab has been shown to improve overall survival in patients with metastatic melanoma; however, complete responses (CRs) are uncommon. Immune-related side effects usually involve the skin or gastrointestinal tract. Neurologic events occur less frequently but are well described. Case Report: We report the case of a 58-year-old man with metastatic melanoma who commenced ipilimumab post spinal decompression and radiation. He developed a colitis post cycle 2 and ipilimumab was discontinued. Imaging, however, documented a radiological CR. 8 weeks later, he developed paraplegia and a myelitis despite an ongoing radiological CR. Steroid use resulted in some improvement radiologically, without clinical improvement. Conclusion: We report myelitis with consequent paraplegia as a potential neurological immune-related side effect of ipilimumab. We further describe a patient with a CR after 2 cycles of ipilimumab in the setting of radiation.

The objective of this paper is to review the data supporting the use of docetaxel in the treatment of breast cancer, focusing on pharmacokinetics, efficacy in adjuvant and metastatic trials alone and in combination with chemotherapeutic and targeted agents, and the toxicity of docetaxel in comparison to paclitaxel. Docetaxel is a semisynthetic product derived from the European yew tree Taxus baccata L. It promotes the assembly of microtubules, stabilizes them, and thereby prevents their depolymerization. Docetaxel has been incorporated into neo-adjuvant chemotherapy regimens, both with and without anthracyclines. The inclusion of taxanes such as docetaxel in polychemotherapy regimens in early breast cancer is associated with a statistically significant reduction in mortality. As a single agent, docetaxel is highly active in the treatment of metastatic breast cancer. In first-line treatment of metastatic breast cancer, the combination of docetaxel and capecitabine was associated with an improvement in overall survival; however, toxicity was higher. The toxicity profile of docetaxel has been well documented and is predictable; the most frequent adverse effects are neutropenia and febrile neutropenia. Taxane-specific adverse effects, such as peripheral neuropathy, are also expected but are manageable with appropriate dosing and scheduling.

the vaccination. Here, we evaluated attitude towards and effects of COVID-19 vaccination in patients with breast or gynecological cancer. The aim was to improve counseling of our patients in clinical routine.Methods: Since March 15 th 2021, patients who received one of the approved COVID-19 vaccines were routinely interviewed about immediate (0-2 days) and late side effects (within two weeks after vaccination). Clinical parameters such as current therapy, time interval between therapy administration and vaccination, and changes in the therapy schedule due to the vaccination were documented. Furthermore, the willingness of non-vaccinated patients to be vaccinated was assessed. The collected data were anonymously analyzed as a part of routine quality assurance.Results: By May 10 th 2021, 111 out of 217 (51.1%) interviewed patients had received at least one shot of COVID-19 vaccine and 21 patients both shots. More than half of the vaccinated patients were >55y (60.2%; mean: 60.7y, range 30-92y); 69% with UICC/ FIGO stage III/IV cancer. 74.6% received Conmirnaty (BioNTech/ Pfizer), 18.9% Vaxzevria (AstraZeneca) and 6.5% Covid-19 Vaccine Moderna. After the first shot, 33.3% of the patients described no side effects, 49.1% reported a local reaction (swelling or pain), 23.4% flu-like symptoms, 10.8% headache and 3.6% nausea. 11 patients had symptoms that lasted longer than two days. In 11 cases, COVID-19 vaccination had an impact on delivery of the systemic therapy (n¼10 postponements of therapy and n¼1 dose reduction). 61.3% of the non-vaccinated patients (in total n¼118) were already registered to get vaccinated; 32.8% chose to postpone vaccination for personal reasons; 5% refused vaccination.Conclusions: Breast and gynecological cancer patients appear to tolerate COVID-19 vaccination well under systemic therapy and only in few cases the vaccination interfered with the treatment schedule. Updated results will be presented at the ESMO Congress.

Tumors of the CNS are among the commonest malignancies occurring in teenage/young adult patients (i.e., those aged between 15 and 24 years). The treatment of this patient population is challenging. Adolescence and young adulthood are a turbulent period of life, with physical, emotional, social and cognitive changes. Best practice advocates their treatment in dedicated teenage/young adult units, with multidisciplinary team input and access to clinical trials. Treatment of CNS malignancies is dependent upon histological subtype and staging, with varying combinations of surgery, radiotherapy and chemotherapy used. Clinical trials directly targeted at this patient population are rare; treatments are based on pediatric protocols as studies have demonstrated improved outcomes in patients (with other malignancies) treated as such. Scope for improvement lies in minimizing patient risk of recurrence and long-term sequelae of treatment. Molecular characterization of tumors may provide further information.

A 65-year-old male patient with stage IIIB non-small-cell lung cancer (squamous cell carcinoma) treated with palliative chemotherapy (carboplatin area under the curve = 5 Day 1, gemcitabine 1250 mg/m 2 Day 1, Day 8 every 21 days), presented on day 10 after cycle 3 of chemotherapy with progressive worsening, including shortness of breath, cough upon drinking fluids, and fever. His pretreatment staging computed tomography (CT) scan showed bulky subcarinal and mediastinal lymphadenopathy (Fig. 1A, white arrow). Upon presentation with the above symptoms, a computed tomography scan of the thorax showed the presence of a fistula (Fig. 1B, white arrow) between the esophagus (single asterisks) and left main bronchus (double asterisks) with evidence of aspiration pneumonia. Subsequently, a bronchial stent was placed in the left main bronchus (Fig. 1C, white arrows) with improvement of his symptoms. The patient did not receive any further systemic treatment because of worsening performance status. He was discharged to the community palliative care team for further management and died 3 months after his presentation and stent placement.
