Effects of perioperative blood transfusion on prognosis in early-stage cervical cancer

Systematic Review and Meta-Analysis on the Role of Perioperative Blood Transfusion in Patients Undergoing Radical Cystectomy for Urothelial Carcinoma

BACKGROUND

Radical cystectomy (RC) is the standard of care in patients with muscle-invasive bladder cancer. The impact of perioperative red blood cell (RBC) transfusion on oncological outcomes after RC is not clearly established as the existing publications show conflicting results.

OBJECTIVES

The aim of this systematic review and meta-analysis was to investigate the prognostic role of perioperative RBC transfusion on oncological outcomes after RC.

METHODS

Systematic online search on PubMed was conducted, based on PRISMA criteria for publications reporting on RBC transfusion during RC. Publications with the following criteria were included: (I) reported data on perioperative blood transfusion; (II) Reported Hazard ratio (HR) and 95% -confidence interval (CI) for the impact of transfusion on survival outcomes. Primary outcome was the impact of perioperative RBC transfusion on recurrence-free survival (RFS), cancer-specific survival (CSS) and overall survival (OS). Risk of bias assessment was performed using Newcastle-Ottawa Scale. Statistical analysis was performed using Revman 5.4 software.

RESULTS

From 27 primarily identified publications, 19 eligible articles including 22897 patients were selected. Perioperative RBC transfusion showed no impact on RFS (Z = 1.34; p = 0,18) and significant negative impact on CSS (Z = 2.67; p = 0.008) and OS (Z = 3.22; p = 0.001). Intraoperative RBC transfusion showed no impact on RFS (Z = 0.58; p = 0.56) and CSS (Z = 1.06; p = 0.29) and OS (Z = 1.47; p = 0.14).Postoperative RBC transfusion showed non-significant trend towards improved RFS (Z = 1.89; p = 0.06) and no impact on CSS (Z = 1.56; p = 0.12) and OS (Z = 0.53 p = 0.60).

CONCLUSION

In this meta-analysis, we found perioperative blood transfusion to be a significant predictor only for worse CSS and OS but not for RFS. This effect may be determined by differences in tumor stages and patient comorbidities for which this meta-analysis cannot control due to lack of respective raw data.

Impact of Blood Transfusions on Survival of Locally Advanced Cervical Cancer Patients Undergoing Neoadjuvant Chemotherapy Plus Radical Surgery

OBJECTIVE

Transfusions represent one of the main progresses of modern medicine. However, accumulating evidence supports that transfusions correlate with worse survival outcomes in patients affected by solid cancers. In the present study, we aimed to investigate the effects of perioperative blood transfusion in locally advanced cervical cancer.

METHODS

Data of consecutive patients affected by locally advanced cervical cancer scheduled to undergo neoadjuvant chemotherapy plus radical surgery were retrospectively searched to test the impact of perioperative transfusions on survival outcomes. Five-year survival outcomes were evaluated using Kaplan-Meier and Cox models.

RESULTS

The study included 275 patients. Overall, 170 (62%) patients had blood transfusion. Via univariate analysis, we observed that transfusion correlated with an increased risk of developing recurrence (hazard ratio [HR], 2.2; 95% confidence interval [CI], 1.09-4.40; P = 0.02). Other factors associated with 5-year disease-free survival were noncomplete clinical response after neoadjuvant chemotherapy (HR, 2.99; 95% CI, 0.92-9.63; P = 0.06) and pathological (P = 0.03) response at neoadjuvant chemotherapy as well as parametrial (P = 0.004), vaginal (P < 0.001), and lymph node (P = 0.002) involvements. However, via multivariate analysis, only vaginal (HR, 3.07; 95% CI, 1.20-7.85; P = 0.01) and lymph node involvements (HR, 2.4; 95% CI, 1.00-6.06; P = 0.05) correlate with worse disease-free survival. No association with worse outcomes was observed for patients undergoing blood transfusion (HR, 2.71; 95% CI, 0.91-8.03; P = 0.07). Looking at factors influencing overall survival, we observed that lymph node status (P = 0.01) and vaginal involvement (P = 0.06) were independently associated with survival.

CONCLUSIONS

The role of blood transfusions in increasing the risk of developing recurrence in LAAC patients treated by neoadjuvant chemotherapy plus radical surgery remains unclear; further prospective studies are warranted.

Laparoscopic versus open radical hysterectomy in early-stage cervical cancer: long-term survival outcomes in a matched cohort study

BACKGROUND

To compare the long-term survival outcomes between laparoscopic radical hysterectomy (LRH) and open radical hysterectomy (ORH).

METHOD

We matched patients with stage IA2 to IIA cervical cancer with known risk factors for recurrence who underwent ORH and LRH.

RESULTS

Compared with ORH (n = 263), LRH (n = 263) did not have higher risks of recurrence [hazard ratio (HR) = 1.28; 95% confidence interval (CI) 0.62-2.64] or death (HR = 1.46; 95% CI 0.62-3.43). Even in patients with tumors >2 cm in diameter, the risks of recurrence (HR = 0.82; 95% CI 0.31-2.16) or death (HR = 1.01; 95% CI 0.35-2.95) were not higher for LRH than for ORH. The LRH and ORH group had 5-year recurrence-free survival rates of 92.8% and 94.4%, respectively (P = 0.499). LRH resulted in significantly lower estimated blood loss (379.6 versus 541.1 ml, P < 0.001) and shorter postoperative hospital stay (12.5 versus 20.3 days, P < 0.001). Intraoperative complication rates were similar in the two groups (6.8% versus 5.7%, P = 0.711), but postoperative complication rate was lower in the LRH than in the ORH group (9.2% versus 21%, P < 0.001).

CONCLUSION

LRH is an oncologically safe alternative to ORH and was associated with fewer postoperative complication and earlier recovery.

Comparison of total laparoscopic and abdominal radical hysterectomy for patients with early-stage cervical cancer

OBJECTIVE

To compare intraoperative, pathologic, and postoperative outcomes of total laparoscopic radical hysterectomy with abdominal radical hysterectomy and pelvic lymphadenectomy for women with early-stage cervical cancer.

METHODS

We reviewed all patients who underwent total laparoscopic radical hysterectomy or abdominal radical hysterectomy and pelvic lymphadenectomy between 2004 and 2006.

RESULTS

Fifty-four patients underwent abdominal radical hysterectomy, and 35 underwent total laparoscopic radical hysterectomy. Mean age was 41.8 years, and mean body mass index 28.1. There was no difference in demographic or tumor factors between the two groups. Mean estimated blood loss was 548 mL with abdominal radical hysterectomy compared with 319 mL with total laparoscopic radical hysterectomy (P=.009), and 15% of patients who underwent abdominal radical hysterectomy required a blood transfusion compared with 11% who underwent total laparoscopic radical hysterectomy (P=.62). Mean operative time was 307 minutes for abdominal radical hysterectomy compared with 344 minutes for total laparoscopic radical hysterectomy (P=.03). On pathologic examination, there was no significant difference in the amount of parametrial tissue, vaginal cuff, or negative margins obtained. A mean 19 pelvic nodes were obtained during abdominal radical hysterectomy compared with 14 during total laparoscopic radical hysterectomy (P=.001). The median duration of hospital stay was significantly shorter for total laparoscopic radical hysterectomy (2.0 compared with 5.0 days, P<.001). For abdominal radical hysterectomy, 53% of patients experienced postoperative infectious morbidity compared with 18% for total laparoscopic radical hysterectomy (P=.001). There was no difference in postoperative noninfectious morbidity. There was no difference in return of urinary function.

CONCLUSION

Total laparoscopic radical hysterectomy reduces operative blood loss, postoperative infectious morbidity, and postoperative length of stay without sacrificing the size of radical hysterectomy specimen margins; however, total laparoscopic radical hysterectomy is associated with increased operative time.

Quality of life and sexual functioning in cervical cancer survivors

PURPOSE

To compare quality of life and sexual functioning in cervical cancer survivors treated with either radical hysterectomy and lymph node dissection or radiotherapy.

METHODS

Women were interviewed at least 5 years after initial treatment for cervical cancer. Eligible women had squamous cell tumors smaller than 6 cm at diagnosis, were currently disease-free, and had either undergone surgery or radiotherapy, but not both. The two treatment groups were then compared using univariate analysis and multivariate linear regression with a control group of age- and race-matched women with no history of cancer.

RESULTS

One hundred fourteen patients (37 surgery, 37 radiotherapy, 40 controls) were included for analysis. When compared with surgery patients and controls using univariate analysis, radiation patients had significantly poorer scores on standardized questionnaires measuring health-related quality of life (physical and mental health), psychosocial distress and sexual functioning. The disparity in sexual function remained significant in a multivariate analysis. Univariate and multivariate analyses did not show significant differences between radical hysterectomy patients and controls on any of the outcome measures.

CONCLUSION

Cervical cancer survivors treated with radiotherapy had worse sexual functioning than did those treated with radical hysterectomy and lymph node dissection. In contrast, these data suggest that cervical cancer survivors treated with surgery alone can expect overall quality of life and sexual function not unlike that of peers without a history of cancer.

[Survival after blood transfusion: a study at Rouen university hospital]

The aim of this study was to estimate short term survival rate after blood transfusion according to various criteria.

PATIENTS AND METHODS

Patients admitted and transfused from January, 1 until June, 30 1996 at Rouen university hospital were retrospectively included, and their status (alive or dead) was determined. The characteristics of patients admitted and transfused were compared to the overall population of inpatients. Independent factors associated with mortality six months after blood transfusion were evaluated using Cox model.

RESULTS

During the study period, 1887 patients were transfused. These patients were older, more often admitted in surgical or in intensive care units, and had a longer duration of stay, than the overall inpatients population. The survival rate at six months in transfused patients was 76.1%. Mortality rate at six months was independently higher in patients aged 75 and older, in men, in patients admitted in intensive care units, or transfused with homologous fresh-frozen plasma or packed platelet blood cells. Mortality rate was lower in patients who underwent a surgical procedure, in children under 16, and in patients whose stay was classified in "Circulatory system disorders", "Musculoskeletal system and connective tissues disorders or trauma", or "Injuries, allergy or poisoning".

CONCLUSION

In this study implemented in a teaching hospital inpatients receiving blood transfusion, the survival was mainly associated with the severity and characteristics of the diseases requiring transfusion.

Effects of the combination of blood transfusion and postoperative infectious complications on prognosis after surgery for colorectal cancer. Danish RANX05 Colorectal Cancer Study Group

BACKGROUND

The frequency of postoperative infectious complications is significantly increased in patients with colorectal cancer receiving perioperative blood transfusion. It is still debated, however, whether perioperative blood transfusion alters the incidence of disease recurrence or otherwise affects the prognosis.

METHODS

Patient risk variables, variables related to operation technique, blood transfusion and the development of infectious complications were recorded prospectively in 740 patients undergoing elective resection for primary colorectal cancer. Endpoints were overall survival (n = 740) and time to diagnosis of recurrent disease in the subgroup of patients operated on with curative intention (n = 532). The patients were analysed in four groups divided with respect to administration or not of perioperative blood transfusion and development or non-development of postoperative infectious complications.

RESULTS

Overall, 19 per cent of 288 non-transfused and 31 per cent of 452 transfused patients developed postoperative infectious complications (P< 0.001). The median observation period was 6.8 (range 5.4-7.9) years. In a multivariate analysis, risk of death was significantly increased among patients developing infection after transfusion (n = 142) compared with patients receiving neither blood transfusion nor developing infection (n = 234): hazard ratio 1.38 (95 per cent confidence interval (c.i.) 1.05-1.81). Overall survival of patients receiving blood transfusion without subsequent infection (n = 310) and patients developing infection without preceding transfusion (n = 54) was not significantly decreased. In an analysis of disease recurrence the combination of blood transfusion and subsequent development of infection (hazard ratio 1.79 (95 per cent c.i. 1.13-2.82)), localization of cancer in the rectum and Dukes classification were independent risk factors.

CONCLUSION

Blood transfusion per se may not be a risk factor for poor prognosis after colorectal cancer surgery. However, the combination of perioperative blood transfusion and subsequent development of postoperative infectious complications may be associated with a poor prognosis.
