Notes

Epidemiology associated with hospitalized melts away inside Romania: A new 10-year study on 92,333 patients.
Our patient is disease-free 16 months after relapse diagnosis. Since recurrence of SLCT has a very poor prognosis and hormonal treatment is contraindicated, endocrine-sparing surgery for young patients with a normal contralateral ovary might be a legitimate option. This is one of the first reported cases of conservative surgery in SLCT recurrence, we therefore aimed to illustrate its management in a young patient with considerations of contraception, fertility- and then endocrine-sparing surgery, and quality of life.Here we describe a case of pleural extranodal marginal zone lymphoma presenting as bilateral chylothorax which has not been reported in the literature prior to this. Primary pleural lymphomas are a rare entity most commonly associated with chronic infections, autoimmune conditions or long-standing pyothorax which were not seen in this case. Chylous pleural effusions in this patient were successfully managed with chemotherapy for the underlying lymphoma.Choriocarcinoma is a malignant tumor that typically appears in gonadal organs and primarily occurs in women of reproductive age. Being a primary extragonadal choriocarcinoma, primary pulmonary choriocarcinoma (PPC) is an extremely rare condition. Due to the rarity of PPC, no standardized treatment has been established so far. However, surgery combined with adjuvant chemotherapy appears to be the most optimal treatment. Here, we report a rare case of a man with PPC that was successfully treated with surgery followed by chemotherapy.Case reports detailing the effects of targeted intraoperative radiation therapy (IORT) on patients with cardiac pacemakers (PMs) are rare. This growing population sub-group requiring IORT and lack of standardized guidelines necessitate more practical published research. An 81-year-old patient with clinical stage II, T1 N0 grade III, triple-negative invasive ductal carcinoma and an implanted single-lead chamber PM (VVIR mode, model Biotronik, type Effecta SR) received targeted intraoperative radiotherapy at the time of wide local excision and sentinel lymph node biopsy. It presents the shortest distance between the outer diameter of the PM and IORT applicator in literature. Target IORT was performed utilizing an Intrabeam device (50 kV, Carl Zeiss Surgical, Oberkochen, Germany). This case elucidates the successful use of targeted IORT for breast-conserving surgery in a patient with a single ipsilateral chamber VVIR mode PM. No device failure or malfunction was reported for the PM before, during, or after the procedure. These findings support the use of targeted IORT for patients diagnosed with early-stage breast carcinomas who have a PM implanted. However, further research is needed to understand the safety of other methods and devices for IORT patients with cardiac implantable electronic devices.Recessive dystrophic epidermolysis bullosa (RDEB) is a genodermatosis that leads to skin fragility and chronic wound formation. Patients with RDEB are at risk for cutaneous squamous cell carcinoma (SCC) which is a major cause of morbidity and mortality in these patients. this website No standard of care exists for the treatment of SCC in this patient population and therapy is based on anecdotal reports and expert opinion. We report a 32-year-old man with RDEB with previously localized SCC who later developed metastatic SCC. He was started on cemiplimab (an immune checkpoint inhibitor) 350 mg IV every 3 weeks. An objective radiological response was noted within 3 cycles. On 14 months follow-up, there was a durable response to treatment clinically and on imaging, without immune-related adverse events. To our knowledge, this is the first case report describing safe administration of immune checkpoint inhibitors in a patient with RDEB with objective and durable response of metastatic SCC. Larger case series and controlled clinical trials are needed to further investigate these medications in the RDEB population, given their high burden of aggressive and often lethal SCC.Metastatic pancreatic ductal adenocarcinoma (PDAC) has a dismal prognosis. Until recently, cytotoxic chemotherapy was the only treatment option. Currently, there are subgroups of patients with PDAC either with somatic or germline mutations who are candidates for targeted agents. Germline mutations in the BRCA1 and BRCA2 genes promote the incapacity of tumor cells to recover from DNA-accumulated damage caused by cytotoxic drugs, like platinum agents, and, most recently, through a diverse process by poly(adenosine diphosphate-ribose) polymerase inhibitor (PARPi). A 59-year-old female who was treated for a triple negative breast cancer 8 years ago with surgery, adjuvant chemotherapy and radiotherapy, presented with increasing back pain. Investigation revealed multiple liver nodules and a large mass in the head of the pancreas. Biopsy confirmed PDAC. She received 13 cycles of FOLFIRINOX, achieving partial response both in the liver and pancreatic lesion, with resolution of symptoms. Due to increasing neuropathy, chemotherapy was stopped, and the patient was followed. Sixteen months later, her CA19-9 levels increased. Given limiting neuropathy, the patient was restarted on FOLFIRI only. After 8 cycles, there was disease progression plus uncontrolled back pain. A mutational test was requested and confirmed a BRCA1 germline mutation. The patient was started on olaparib. After 3 cycles, images showed a significant response and after 6 cycles, it remained stable, with persistent fall in CA19-9 levels. She is currently on treatment, with ongoing response. In conclusion, patients with metastatic PDAC and BRCA mutation may benefit from PARPi even after progression on chemotherapy. We hypothesize that olaparib works even in the setting of disease progression and not solely as a maintenance therapy following platinum-based therapy. Randomized trials are needed investigating the role of olaparib following disease progression in PDAC.The use of circulating cell-free tumour DNA (ctDNA) is established in metastatic lung adenocarcinoma to detect and monitor sensitising EGFR mutations. In early-stage disease, there is very little data supporting its role as a potential biomarker. We report on a prospective cohort of 9 limited-stage EGFR mutant lung cancer patients who were treated with radical radiotherapy. We looked at baseline plasma EGFR ctDNA and noted the detection rates to be higher in locally advanced disease. At a median follow-up of 13.5 months, an association between a detectable pre-radiotherapy plasma EGFR ctDNA and early tumour relapse (155 days vs. NR, p = 0.004) was noted. One patient with persistent plasma EGFR ctDNA predated radiological progression. The role of ctDNA in early-stage lung cancer is developing. Plasma EGFR ctDNA could be a useful biomarker in lung cancer patients undergoing radical treatments for staging, prognostication, and follow-up. These preliminary findings should be explored in larger studies.
