Clinical characteristics, treatment patterns and relapse in patients with clinical stage IS testicular cancer.

PURPOSE: Clinical stage I (CSI) testicular germ cell tumors (TGCT) represents disease confined to the testis without metastasis and CSIS is defined as persistently elevated tumor markers (TM) after orchiectomy, indicating subclinical metastatic disease. This study aims at assessing clinical characteristics and oncological outcome in CSIS. METHODS: Data from five tertiary referring centers in Germany were screened. We defined correct classification of CSIS according to EAU guidelines. TM levels, treatment and relapse-free survival were assessed and differences between predefined groups (chemotherapy, correct/incorrect CSIS) were analyzed with Fisher's exact and Chi-square test. RESULTS: Out of 2616 TGCT patients, 43 (1.6%) were CSIS. Thereof, 27 were correctly classified (cCSIS, 1.03%) and 16 incorrectly classified (iCSIS). TMs that defined cCSIS were in 12 (44.4%), 10 (37%), 3 (11.1%) and 2 (7.4%) patients AFP, ß-HCG, AFP plus ß-HCG and LDH, respectively. In the cCSIS group, six patients were seminoma and 21 non-seminoma. Treatment consisted of active surveillance, carboplatin-mono AUC7 and BEP (bleomycin, etoposide and cisplatin). No difference between cCSIS and iCSIS with respect to applied chemotherapy was found (p = 0.830). 5-year relapse-free survival was 88.9% and three patients (11%) in the cCSIS group relapsed. All underwent salvage treatment (3xBEP) with no documented death. CONCLUSION: Around 1% of all TGCT were classified as cCSIS patients. Identification of cCSIS is of critical importance to avoid disease progression and relapses by adequate treatment. We report a high heterogeneity of treatment patterns, associated with excellent long-term survival irrespective of the initial treatment approach.

[Perception of the COVID-19 Pandemic among Pneumology Professionals in Germany]. / Wahrnehmung der COVID-19-Pandemie unter pneumologischen Fachkräften in Deutschland.

The COVID-19 pandemic represents a huge burden on global health systems. Although far-reaching prevention measures such as the increase of intensive care capacities and drastic restrictions of public life have so far been able to avert an overload of the German health care system, the current situation implies an exceptionally high burden on medical professionals. The current study presents the results of an opinion evaluation among 513 pneumology specialists in Germany in the period from March 27th to April 11th, 2020. While the majority of respondents stated that Germany was "well" prepared for the pandemic, this assessment was significantly worse among participants from the outpatient sector compared to the hospital sector (p < 0.001). Furthermore, a lack of medical protective equipment was reported significantly more frequently by respondents from the outpatient sector (p < 0.001). The importance of telemedicine approaches during the COVID-19 pandemic was rated "high" (35.2 %) or "very high" (17.2 %) by most pneumology professionals, with participants from the hospital sector giving a higher rating (p < 0.001). Finally, 45.8 % of the respondents expressed a "negative" influence of the COVID-19 pandemic on their personal mood and 58.3 % expressed "strong" or "very strong" concerns about the health of their fellow human beings. This assessment was significantly stronger among female participants and participants from the nursing sector (p < 0.001). In summary, the current study analyses for the first time the professional and personal impact of the COVID-19 pandemic on pneumology professionals in Germany. The results could help to identify first starting points to better support health professionals during the current and future challenges.
