We present demographic, clinical, laboratory characteristics and outcomes of the patients with solid malignancies and novel coronavirus disease (COVID‐19) collected from the National COVID‐19 ...Registry of Turkey. A total of 1523 patients with a current or past diagnosis of solid tumors and diagnosed with COVID‐19 (confirmed with PCR) between 11 March and 20 May 2020 were included. The primary outcome was 30‐day mortality. Median age was 61 (range: 18‐94), and 752 (49%) were male. The most common types of cancers were breast (19.8%), prostate (10.9%) and colorectal cancer (10.8%). 65% of the patients had at least one comorbidity. At least one COVID‐19‐directed therapy was given in 73% of the patients.. Hospitalization rate of the patients was 56.6% and intensive care unit admission rate was 11.4%. Seventy‐seven (5.1%) patients died within 30 days of diagnosis. The first multivariate model which included only the demographic and clinical characteristics showed older age, male gender and presence of diabetes and receipt of cytotoxic therapy to be associated with increased 30‐day mortality, while breast and prostate cancer diagnoses were associated with lower 30‐day mortality. In the second set, we further included laboratory parameters. The presence of leukocytosis (OR 6.7, 95% CI 3.3‐13.7, P < .001), lymphocytopenia (OR 3,1, 95% CI 1,6‐6,1, P = .001) and thrombocytopenia (OR 3,4 95% CI 1,5‐8,1, P = .005) were found to be associated with increased 30‐day mortality. Relatively lower mortality compared to Western countries and China mainly results from differences in baseline risk factors but may also implicate the importance of intensive supportive care.
What's new?
Patients with cancer represent a vulnerable population to COVID‐19 due to the immune‐suppressive effect of the treatment and disease itself, their older age, and the frequent presence of comorbid diseases. In this cohort analysis of 1523 patients with solid tumors diagnosed with COVID‐19, the 30‐day mortality rate was found to be 5.1%. Cancer type, older age, male gender, diabetes, and cytotoxic treatment within 4 weeks were significant clinical predictors of increased mortality. The relatively lower mortality compared with Western countries and China mainly results from differences in baseline risk factors, but may also implicate the importance of intensive supportive care.
Objective
The objective of this study is to determine whether 2-deoxy-2-18F fluoro-
d
-glucose with positron emission tomography (FDG-PET) imaging and quantitative PET parameters can predict outcome ...and differentiate patients with limited disease (LD) from extensive disease (ED) in patients with small cell lung cancer (SCLC).
Methods
We retrospectively evaluated data from 25 patients who underwent either initial staging (Group A,
n
12) or restaging (Group B,
n
13) by conventional imaging methods and FDG-PET according to the simplified staging scheme developed by the Veterans Administration Lung Cancer Study Group-2. FDG-PET images were both visually and quantitatively evaluated with SUV
max
, SUV
ave
, total metabolic tumor volume (with SUV
max
> %50 and SUV
max
> 2.5), total lesion glycolysis (TLG) (with SUV
max
> %50 and SUV
max
> 2.5). The correlation between quantitative PET parameters, disease stages and survival were analyzed.
Results
By conventional methods 14 of 25 (56%) patients were reported to have LD and 11 of 25 (44%) had ED. FDG-PET scan upstaged 9 out of 25 (36%) and downstaged 2 out of 25 (%8) patients. Among the quantitative PET parameters, TLGs were the only PET parameters that differentiated between Group A and Group B patients. FDG-PET staging (
p
= 0.019) could predict significant survival difference between stages on contrary to conventional staging (
p
= 0.055). Moreover, TLG SUV
max
> %50 was the only quantitative PET parameter that could predict survival (
p
= 0.027).
Conclusion
FDG-PET imaging is a valuable tool in the management of patients with SCLC for a more accurate staging. The use of quantitative PET parameters may have a role in prediction of stage and survival.
Metaplastic breast carcinoma (MpBC) is a rare disease entity, accounting for less than 1% of all breast carcinomas. Furthermore, it is a heterogenous disease with different subgroups, including ...malignant epithelial (carcinoma) and stromal (sarcoma) features. Here we evaluated, retrospectively, 14 female MpBC patients admitted to Ankara Oncology Training and Research Hospital between 2005 and 2011. Median age was 45.5 (range:16.0-76.0) and tumor size 57.5 mm (range: 20.0-80.0 mm). Histopathological subtypes were as follows: 5 carcinosarcoma, 5 squamous and 4 adenosquamous carcinoma. All but one with upfront lung metastasis, had their primary breast tumor operated. Axillary lymph nodes were involved in 64.3%. The most common sites of metastasis were lungs and brain. Chemotherapy including antracycline, taxane and even platinium was planned for adjuvant, neoadjuvant and palliative purposes in 9, 3 and 1 patient, respectively. Median cycles of chemotherapy was 6 (range:4-8). Median follow-up of the patients was 52 months (95%CI 10.4-93.6 month). Median 3 year progression free survival (PFS) and overall survival (OS) in this patients cohort were 33% and 56%, respectively. In conclusion, MpBC is a rare and orphan disease without standardized treatment approaches and the prognosis is poor so that larger studies to investigate different treatment schedules are urgently needed.
Aim of the study was to investigate the demographics of Ewing sarcoma family of tumours (ESTF) patients, treatment alternatives, clinical outcomes, and prognostic factors for survival.
We ...retrospectively reviewed 39 patients with ESFT who were admitted to our institute between September 2008 and September 2012.
The patients included 32 (82.1%) males and seven (17.9%) females of median age 24 (range, 18-66) years. Among the 27 patients with a primary osseous localization, 17 (43.5%) had a central axis localization. Fifteen patients (38.5%) had metastases at the time of diagnosis. Patients were followed up for a median period of 18 (range, 2-134) months. The median event-free survival (EFS) was 23 (range, 1-64) months, and the 1- and 4-year EFS were 60% and 48%, respectively. The median overall survival (OS) was 91 (range, 1-188) months, and the 1- and 4-year OS were 78% and 54%, respectively. Gender, age, primary tumor site, and local treatment modalities, either alone or in combination, did not have a significant effect on OS (p = 0.210, p = 0.617, p = 0.644, and p = 0.417, respectively). In contrast, osseous site of peripheral localization, limited stage, and metastasis to the bone significantly affected OS (p = 0.015, p < 0.001, and p = 0.042, respectively).
ESFTs are aggressive tumors with a high rate of relapse and metastatic potential. Patients with peripheral bone involvement and limited stage had a good prognosis. Appropriate surgical resection, radiotherapy, and aggressive chemotherapy regimens are recommended.
Primary sternal malignant fibrous histiyocytoma (MFH) is highly rare. Effective treatment modality is surgical resection with wide margins. However, to date, the effects of radiotherapy or ...chemotherapy has not been clearly defined.
Herein, we aimed to present a 50-year old female patient with MFH occurred in the radiotherapy field who had had surgical procedure for breast cancer 19 years ago and had followed by radiotherapy. Neoadjuvant chemotherapy was applied for MFH due to cardiac and mediastinal vascular invasion. Wide resection was carried out for the mass after having been decreased in size following neoadjuvant chemotherapy.
Neoadjuvant chemotherapy was an effective method. In planning the surgical resection, the size of the tumor before chemotherapy should be considered as the initial size and surgical margins should be determined accordingly.
The aim of this study was to assess the use of 5-fluorouracil (5-FU), leucovorin and oxaliplatin (FOLFOX) regimens in clinical practice according to their efficacy and toxicity.
Patients who received ...oxaliplatin-containing regimens after curative resection for colorectal carcinoma from 10 different oncology centers between May 2004 and December 2009 were included in the study. All patients were treated with FOLFOX regimens. Patients with rectal carcinoma were also treated with chemoradiotherapy with 5-FU after 2 cycles of a FOLFOX regimen.
The median age of the patients was 56 years (range 17-78). Of the total 667 patients, 326 were given FOLFOX-4, 232 were given modified FOLFOX-4 and 109 were given FOLFOX-6. The distribution according to disease stage was 33 patients with stage IIIA colorectal cancer, 382 patients with stage IIIB and 252 patients with stage IIIC. The most common adverse events were neutropenia (54%), nausea (36.9%), neuropathy (38.2%) and anemia (33.1%) for all grades. The median follow-up time was 23 months (range 1-79). Three-year disease-free survival and overall survival were 65 and 85.7%, respectively.
The different oxaliplatin-containing 5-FU-based adjuvant chemotherapy regimens in patients with stage III colorectal cancer seemed to be at least equal in terms of efficacy regardless of the method of 5-FU administration or oxaliplatin dose.
Trastuzumab prolonged the overall survival in patients with advanced gastric cancer with human epidermal growth factor receptor 2 (HER2) overexpression in combination with chemotherapy. In this phase ...II open-label prospective study, the tolerability and safety of trastuzumab with chemotherapy, and chemoradiotherapy for curatively resected patients with HER2-positive gastric carcinoma was investigated.
The patients with HER2-positive gastric, or gastroesophageal junction adenocarcinoma, after gastrectomy plus D2 dissection, were included. They received 3 cycles of oxaliplatin (100 mg/m2 intravenously day 1) plus capecitabine (850 mg/m2 orally days 1 to 14), trastuzumab (8 mg/kg intravenously day 1 in cycle 1, 6 mg/kg thereafter) every 21 days, followed by chemoradiotherapy. Trastuzumab was given for 1 year.
Of the 212 patients screened, 35 were eligible, and 34 were treated. The median age was 56 years (minimum to maximum: 35 to 75 y), male patients constituted 73.5% (n=25), and 33 (97.1%) had gastric adenocarcinoma. R0 resection was performed in 30 (88.2%). The majority (26, 61.7%) were in stage III disease. Most of the adverse events were grade I/II, the most frequent grade III side effects were nausea (3, 8.8%), vomiting (3, 8.8%), diarrhea (2, 5.9%), and weight loss (n=2, 5.9%). Two patients died during the first 3 cycles of chemotherapy and chemoradiotherapy; 1 secondary to pulmonary thromboembolism, and the other due to cerebral ischemia. After excluding 2 with early progression and 1 consent withdrawal, of the remaining 31 patients, 28 (90.3%) were able to complete the chemotherapy and chemoradiotherapy part of the trial. After the 25 months follow-up period, 21 patients (61.8%) were alive. Overall survival at 12 and 24 months was 75.0% and 58.0%, while disease-free survival at 12 and 24 months was 65.7% and 55.0%, respectively.
Trastuzumab in combination with capecitabine, oxaliplatin following chemoradiotherapy as the adjuvant therapy for gastric or gastroesophageal junction adenocarcinoma was considered as safe and tolerable. The frequency of HER2 overexpression in curatively resected patients is comparable to that in patients with metastatic disease (trial registration: clinicaltrials.gov the identifier: NCT01748773, December 13, 2012, https://clinicaltrials.gov/ct2/show/NCT01748773).

Background: We evaluated the safety and tolerability of trastuzumab (T) in combination with oxaliplatin (O), capecitabine (C) and chemo-radiotherapy in the adjuvant setting in ...operated, HER-2 positive gastric or gastroesophageal junction adenocarcinoma patients. Methods: We have screened 212 and enrolled 34 patients who were curatively resected (R0, R1 with partial or total gastrectomy, with D2 lymph node dissection) and were HER2-positive (IHC 2+/FISH+ or IHC 3+). The primary objectives were safety and tolerability of the treatment combination and secondary objectives were disease-free and overall survival rates. Patients received T 8 mg/kg intravenously (iv) on Day 1 of cycle 1 and 6 mg/kg iv on day 1 of every following 3-weekly cycle for 1 year as 17 cycles, O 100 mg/m2 iv on Day 1 of cycles 1-3 and C 850 mg/m2 orally twice daily on days 1-14 of cycles 1-3 and 5 days per week during chemo-radiotherapy. Radiotherapy was given at a total dose of 45 Gy divided into 25 doses 5 treatment days per week for 5 weeks starting from the 1st day of cycle 4. Results: The median age was 57 years and 73.5% were male, 97.0% had an ECOG PS score ≤ 1,33, 97.0% had D2 lymph node resection. Staging was 3A or higher at the time of diagnosis in 76.4% of patients. Patients had high rate of tolerability to the combination regimen (90.3%) and successfully completed 3 cycles of O+C+T plus chemoradiotherapy followed by continuation with T, achieving the primary goal of the study by showing a better tolerability rate as compared to tolerability reported for INT0116 study (p = 0.0068). After 25 months of follow-up confirmed through a telephone visit, 59.8% patients were still alive and median overall survival was not yet reached. Twelve patients died secondary to disease progression. There were no deaths due to toxicity and 6 dose reductions overall (1 for T, 2 for O and 3 for C). T was stopped in one patient; C was temporarily interrupted 11 times (mostly during radiotherapy) and stopped in 1 patient. Conclusions: T in combination with C, O and radiotherapy in the adjuvant setting for gastric or gastroesophageal junction adenocarcinoma seems safe and tolerable. Clinical trial information: NCT01748773.

Background: Trastuzumab in combination with chemotherapy has been shown to prolong survival of HER2+ esophago-gastric cancer patients. The primary aim of our study was to ...evaluate safety and tolerability of trastuzumab (T) in combination with oxaliplatine (O), capecitabine (C) and radiation (R) therapy in the adjuvant setting in curatively resected esophago-gastric cancer patients. Methods: Forty patients with IB or higher stages was planned to be recruited and here we report the interim analyses on 22. We would consider the study positive if at least 64.4% of patients could tolerate the therapy. Eligible patients received T 8 mg/kg intravenously (iv) on Day 1 of cycle 1 and 6 mg/kg iv on day 1 of every following 3-weekly cycle for 1 year as 17 cycles, with O 100 mg/m2 iv on Day 1 of cycles 1-3 and C 850 mg/m2 orally twice daily on days 1-14 of cycles 1-3 and on 5 days per week during chemo-radiotherapy. R was given at a total dose of 45 Gy divided into 25 doses on 5 treatment days per week for 5 weeks starting from the 1st day of cycle 4. Results The median age was 57.5 years (Min-Max: 35-74). Of 22 patients; 15 were male (68.2%), 21 (95.5%) had an ECOG PS score ≤ 1, 21 (95.5%) had D2 lymph node resection. There were 11 serious adverse events. Two patients died on therapy; 1 secondary to pulmonary thrombo-emboli, and the other had to cerebral ischemia (thought to be due to Behçet’s disease), and 7 died of progression. There were 6 dose reductions (1 for T, 2 for O and 3 for C), T was stopped in 1 patient, C was interrupted 8 times (mostly during radiotherapy). Patients who have completed 3 cycles of O, C, T and 4th and 5th cycles of chemo-radiation therapy with C and T were defined as tolerable. Out of 22 patients, 19 (86.4%) were tolerable (Chi Square test: p = 0.0623). Median survival time for interim analysis patients (n = 22) was 22 months (95% CI: 11-23 months). Conclusion T in combination with O, C and chemo-radiation with C and T was tolerable with the tolerability rate of 86.4%, in curatively resected HER2 + esophago-gastric cancer adjuvant treatment. Clinical trial information: NCT01748773.
To examine the impact of the workforce crisis on healthcare service delivery for a year during the coronavirus disease 2019 (COVID-19) pandemic on healthcare service delivery and hospital economy in ...a healthcare facility.
An examination was conducted of employees who were issued with a report for incapacity to work due to the pandemic between March 2020 and March 2021. A record was made of the employees' ages, genders, fields of work and lost workdays. The employees were classified as physicians, nursing services, guest services, hotel services, and support services. Diagnoses were made of the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), based on computed tomography (CT) and polymerase chain reaction (PCR) test results. Employees diagnosed with SARS-CoV-2 infection were put into isolation in the hospital during the first months of the pandemic, and treatment was initiated in accordance with the protocols. By contrast, during the last eight months, our personnel who were not indicated for hospitalization completed their treatment in a home isolation setting. According to the Turkish Ministry of Health COVID-19 (SARS-CoV-2 Infection) Scientific Advisory Board Study Guide, the isolation period was initially 14 days, before being reduced to 7-10 days, in line with the revised guide. Employees with at least one negative PCR test result following isolation were allowed to return to work.
The study included 575 individuals who were employed at our hospital between March 2020, when the first case was identified in Turkey, and March 2021. Among these employees, 257 were issued with a report for incapacity to work due to COVID-19. Of these, 239 had a positive PCR test result. There were 11 individuals who just had symptoms and/or positive CT findings but a negative PCR test result. There were only seven individuals who were put into isolation due to high-risk contact. The combined lost workdays of the employees totaled 3792. The highest lost workday rate (52%) was in nursing services (1973 days, n = 126). There was no mortality. Conclusion: Lost workdays due to the pandemic in the midsize healthcare facility severely affected the morale and motivation of both the diagnosed and the remaining employees. Hospital administrations also had difficulties in maintaining the quality and continuity of the services provided.
