RESUMO
Background: Data on the efficacy and safety of COVID-19 vaccines in patients with malignancy are immature. In this paper, we assessed the literature involving the use of COVID-19 vaccines in cancer patients and reported the seroconversion rates as the main outcome and severity of COVID-19 infection and side effects following COVID-19 vaccination as the secondary outcomes. Methods: A systematic review with meta-analysis was performed. Searches were conducted in electronic websites, databases, and journals, including Scopus, PubMed, Embase, and Web of Science from January 01, 2019, to November 30, 2021. Studies reporting data on the safety and efficacy of COVID vaccine in cancer patients using any human samples were included. The risk of bias was assessed using the NEWCASTLE-OTTAWA scale in the included studies. Results: A total of 724 articles were identified from databases, out of which 201 articles were duplicates and were discarded. Subsequently, 454 articles were excluded through initial screening of the titles and abstracts. Moreover, 41 studies did not report the precise seroconversion rate either based on the type of cancer or after injection of a second dose of COVID vaccine. Finally, 28 articles met all the inclusion criteria and were included in this systematic review. The overall seroconversion rates after receiving a second dose of COVID-19 vaccine, based on type of cancer were 88% (95% CI, 81%-92%) and 70% (95% CI, 60%-79%) in patients with solid tumors and hematologic malignancies, respectively. Conclusion: Overall, we conclude that vaccination against COVID-19 in patients with active malignancies using activated and inactivated vaccines is a safe and tolerable procedure that is also accompanied by a high efficacy.

OBJECTIVE: To determine the clinical characteristics and outcomes of COVID-19 in a large cohort of new cancer patients referred to an oncology clinic in the north of Iran. METHODS: During the 20-month COVID-19 pandemic, new cancer patients were followed-up. Demographic, pathologic, and clinical variables were collected for each patient. COVID-19 was confirmed based on a positive polymerase chain reaction test. Analyses were performed using the STATA version 14.0 at a significance level of 0.05. RESULTS: In this study, 1294 new cancer patients were followed for 24 months (mean age: 58.7 years [range 10-95]). During the study period, COVID-19 was diagnosed in 9.4% of the patients with hospitalization rate of 3.4%, an ICU admission rate of 0.7%, and COVID-19 mortality rate of 4.9%. Hematological malignancies (ORU= 2.6, CI95% 1.28-5.34), receiving palliative treatments (ORA=3.03, CI95% 1.6-5.45) and receiving radiotherapy (ORA=2.07, 1.17-3.65) were the most common predictive factors of COVID infection in cancer patients. Also, the COVID mortality was higher in brain cancer patients (p = 0.07), metastatic disease (p = 0.01) and patients receiving palliative treatments (p = 0.02). CONCLUSION: In patients suffering from cancer, COVID-19 infection can be predicted by cancer type, palliative care, and radiotherapy in cancer patients. Furthermore, brain cancers, metastasis, and palliative care were all associated with COVID-19-related mortality.

Aim: To determine the efficacy and safety of inactivated SARS-CoV-2 vaccine (BBIBP-CorV) in patients with breast cancer. Methods: In this multi- institutional cohort study, a total of 160 breast cancer patients (mean age of 50.01 ± 11.5 years old) were assessed for the SARS-CoV-2 Anti-Spike IgG and SARS-CoV2 Anti RBD IgG by ELISA after two doses of 0.5 mL inactivated, COVID-19 vaccine (BBIBP-CorV). All patients were followed up for three months for clinical COVID-19 infection based on either PCR results or imaging findings. Common Terminology Criteria for Adverse Events were used to assess the side effects. Results: The presence of SARS-CoV-2 anti-spike IgG, SARS-CoV2 anti-RBD IgG, or either of these antibodies was 85.7%, 87.4%, and 93.3%. The prevalence of COVID-19 infection after vaccination was 0.7%, 0% and 0% for the first, second and third months of the follow-up period. The most common local and systemic side-effects were injection site pain and fever which were presented in 22.3% and 24.3% of patients, respectively. Discussion: The inactivated SARS-CoV-2 vaccine (BBIBP-CorV) is a tolerable and effective method to prevent COVID-19.

Brain tumors are the rarest cause of cerebrospinal fluid rhinorrhea. Non-traumatic cerebrospinal fluid rhinorrhea is also a relatively rare condition. It may be misdiagnosed as allergic rhinitis or chronic sinusitis and lead to unsuitable treatment. We described a 34-year-old man who came to our allergy clinic with a chief complaint of clear rhinorrhea from his left nostril with more than four years of duration. Onlyhypertrophy of left inferior concha was found in the clinical examination. His rhinorrhea aggravated when bending forward. So we were suspicious of CSF rhinorrhea. MRI was done for him and demonstrated a large tumor in the pineal region. The patient underwent surgery with resection of the mass via an infratentorial-supracerebellar approach. This case showed the role of maintaining differential diagnosis for a common complaint; rhinitis which is seen as usual.

Immunotherapy is the standard of treatment for long-life relief of symptoms of allergic rhinitis. Vitamin D may affect the outcomes of treatment. This study evaluated the clinical efficacy of subcutaneous allergen immunotherapy in adult patients with allergic rhinitis based on the serum level of vitamin D. Patients with persistent allergic rhinitis and positivity for skin prick test were evaluated by Sino-nasal Outcome Test (SNOT-22) and Mini Rhinoconjunctivitis Quality of Life Questionnaire (MiniRQLQ) before subcutaneous allergen immunotherapy and during the maintenance phase to assess the relation of the serum level of vitamin D and the clinical efficacy of immunotherapy. After immunotherapy, the greatest reduction in SNOT-22 scores were reported in patients with vitamin D sufficiency (39.0 ± 9.2), followed by vitamin D suboptimal provision (35.1 ± 12.1), insufficiency (25.0 ± 7.5), and deficiency (18.3 ± 6.0) (P < 0.001). The MiniRQLQ reduction in patients with vitamin D sufficiency, suboptimal provision, insufficiency, or deficiency was 30.7 ± 8.7, 27.1 ± 8.7, 20.0 ± 8.6, or 17.4 ± 7.1, respectively (P < 0.001). Both of SNOT-22 and MiniRQLQ scores decreased significantly following immunotherapy in patients with different levels of vitamin D. However, these effects were more pronounced when the level of vitamin D was sufficient.
