Impact of the COVID-19 Pandemic on Treatment and Oncologic Outcomes for Cancer Patients in Romania.

BACKGROUND/AIM: This study aimed to assess the impact of the ongoing COVID-19 pandemic on cancer patients, known to be immune-compromised due to the disease itself, oncological treatments and adjuvant medicines use such as steroids. Overall survival was determined for patients with COVID-19 infection and stratification according to known comorbidities and complications was performed. PATIENTS AND METHODS: This prospective study included ninety cancer patients with COVID-19 confirmed by PCR testing performed before each cycle of chemotherapy or every two weeks during radiotherapy between May and December 2020 in two tertiary Cancer Centers. Demographic, cancer-related and SARS-CoV-2 infection data were collected and long-term oncologic outcome was assessed. RESULTS: Mean age of cancer patients diagnosed with SARS-CoV-2 was 59.7±12.1 years (range=30-83 years). Fifty-two (57.7%) were women. The most frequent cancer localization was breast (n=28, 31.1%) followed by colorectal (n=11, 12.2%) and lung cancer (n=8, 8.8%). Most patients infected with SARS-CoV-2 were diagnosed in stage IV of the disease (n=44, 48.9%) followed by stage III (n=19, 21.1%) and stage II disease (18.9%). Regarding comorbidities, the most common was hypertension (n=31) followed by cardiac dysfunction (n=23) and type II diabetes (n=13). Of 27 (30%) patients who needed hospitalization, 4 patients developed severe infection, 17 patients had mild symptoms and 6 patients were minimally symptomatic. After a median follow-up of 22.5 months, 5 patients (5.55%) died due to SARS-COV-2 infection, all stages III and IV. Median estimated overall survival was 14 months in patients who died because of COVID infection compared to 98 months in cancer-related mortality analysis (p<0.0001). Three deaths occurred during chemotherapy, 1 death in the chemoradiotherapy radiotherapy group. CONCLUSION: SARS-CoV-2 infection was associated with an excess mortality in our study population, especially in patients with advanced and metastatic disease and in those receiving immunosuppressive treatment such as chemotherapy and radiotherapy.

A Prospective Observational Study of 42 Patients with COVID-19 infection and a History of Hepatitis C Virus Infection and Thyroid Disease with Follow-Up Thyroid Function and Autoantibody Testing.

BACKGROUND Thyroiditis is an important extrahepatic association in chronic hepatitis C virus (HCV) infection. There have been reports of an association between SARS-CoV-2 infection and the onset or re-activation of autoimmune hypothyroidism. Therefore, we performed this prospective observational study of 42 patients with COVID-19 infection and a history of hepatitis C virus infection and thyroid disease with follow-up thyroid function and autoantibody testing. MATERIAL AND METHODS From April 2020 to October 2020, we performed a prospective observational study of patients with cured hepatitis C virus (HCV) infection and documented thyroid disease who became infected with SARS-CoV-2 (confirmed by SARS-CoV-2 RNA detection via reverse-transcription polymerase chain reaction [RT-PCT] from the upper respiratory tract, both nasal and pharyngeal swabs). Evaluation at 1 and 3 months after SARS-CoV-2 infection included serum determination of antithyroid antibodies (anti-thyroglobulin [anti-Tg] and antithyroid peroxidase [ATPO]), thyroid-stimulating hormone (TSH), free thyroxine (fT4), free triiodothyronine (fT3), and evaluation of thyroid medication, with dose adjustment if required. RESULTS One-month follow-up showed that both patients with autoimmune thyroiditis as well as patients without antibodies had increased ATPO levels. Also, levels of TSH, fT3, and fT4 were significantly decreased. At 3-month follow-up, levels of ATPO were decreased in all patient groups and the levels of thyroid hormones increased to normal values. CONCLUSIONS This study supports previous reports of an association between SARS-CoV-2 infection and thyroid dysfunction associated with thyroid autoantibodies. Thyroid function tests may be considered as part of the laboratory work-up in patients with COVID-19.

Lung Cancer, Covid-19 Infections and Chemotherapy.

BACKGROUND/AIM: The Covid-19 epidemic has severely strained health care systems across the globe. The impacts are multiple especially for patients cared for cancer. The Covid-19 epidemic has several impacts on the management of lung cancer patients. The aim of this work was to summarize the available epidemiological data on patients diagnosed with lung cancer infected with Covid-19 and describe the different strategies to improve the management of these patients by summarizing the recommendations in this area. PATIENTS AND METHODS: The Teravolt cohort is an observational multicenter registry, including patients with non-small cell cancer, small cell cancer or mesothelioma but also epithelial tumors and a diagnosis of Covid-19. The Theravolt registry indicates an unexpectedly high mortality rate in patients with thoracic malignancies with COVID-19. RESULTS: Between March 26 and April 12, 2020, 200 patients treated in 8 countries were included. They had a performance status (PS) of 0-1 in 72% of cases, were smokers or ex-smokers in 81% of cases, had non-small cell cancer (76% of cases), were under treatment in 74% of cases, and the majority were first-line cases (57%). The hospitalization rate was 76% and the mortality rate 33%; only 10% of patients with criteria for intensive care hospitalization were admitted to the intensive care. CONCLUSION: Data presented in this registry suggest a high mortality in patients with thoracic cancer and Covid-19. Therofere, the importance to create a safe healthcare system during Covid-19 pandemic is underlined along with the need for essential effective clinical service delivery to patients with lung cancer.

Long-term Response After Stopping Immunotherapy in a Patient With Metastatic Renal Cancer.

BACKGROUND/AIM: Kidney cancers account for about 2% of human malignancies. In recent decades, the incidence of this cancer type has gradually increased, mainly due to advances in imaging. The metastatic potential of these cancers is significant: a quarter of patients will immediately present with metastases and more than one third of patients treated with nephrectomy for a localized disease will develop metastases during their course. In total, more than half of patients will suffer from the consequences of metastasis. The median survival at this stage is only thirteen months, so the therapeutic challenge is immense. CASE REPORT: The present case report describes a case of left renal clear cell carcinoma with brain, lung, right adrenal, bone and lymph node metastases in a 55-year-old male. The patient received only one line of anticancer treatment with sunitinib, which could not be continued due to haemorrhagic manifestations in brain metastases. The treatment was changed with immunotherapy which showed its effect even if it was stopped due to the patient wishes in the context of the COVID-19 epidemic. CONCLUSION: Immunotherapy opens the doors to a new era in treatment of metastatic renal cancer and shows efficiency even after it has been stopped.
