Abstract

Surgical resection remains the best option for long-term survival in many solid tumors. Surgery can, however, lead to tumor cell release into the circulation. Data have suggested differential effects of anesthetic agents on cancer cell growth. This retrospective analysis investigated the association of anesthetic technique with long-term survival in patients presenting for elective surgery in a comprehensive cancer center over 3 yr.

Anesthetic technique for radical prostatectomy surgery affects cancer recurrence: a retrospective analysis.

Denis Moriarty, Darren Fitzpatrick, D Buggy … (2008)

Regional anesthesia and analgesia attenuate or prevent perioperative factors that favor minimal residual disease after removal of the primary carcinoma. Therefore, the authors evaluated prostate cancer recurrence in patients who received either general anesthesia with epidural anesthesia/analgesia or general anesthesia with postoperative opioid analgesia. In a retrospective review of medical records, patients with invasive prostatic carcinoma who underwent open radical prostatectomy between January 1994 and December 2003 and had either general anesthesia-epidural analgesia or general anesthesia-opioid analgesia were evaluated through October 2006. The endpoint was an increase in postoperative prostate-specific antigen. After adjusting for tumor size, Gleason score, preoperative prostate-specific antigen, margin, and date of surgery, the epidural plus general anesthesia group had an estimated 57% (95% confidence interval, 17-78%) lower risk of recurrence compared with the general anesthesia plus opioids group, with a corresponding hazard ratio of 0.43 (95% confidence interval, 0.22-0.83; P = 0.012) in a multivariable Cox regression model. Gleason score and tumor size (percent of prostate involved) were also independent predictors of recurrence (hazards ratios of 1.19 [1.08, 1.52], P = 0.004, and 1.17 [1.03, 1.34] for 10% size difference, P = 0.01, respectively). A similar association between epidural use and recurrence was obtained by comparing patients matched on the propensity to receive epidural versus general anesthesia. Open prostatectomy surgery with general anesthesia, substituting epidural analgesia for postoperative opioids, was associated with substantially less risk of biochemical cancer recurrence. Prospective randomized trials to evaluate this association seem warranted.

Suppression of natural killer cell activity and promotion of tumor metastasis by ketamine, thiopental, and halothane, but not by propofol: mediating mechanisms and prophylactic measures.

Nadav Bar, Keren Shakhar, R. Melamed … (2003)

Postoperative immunosuppression is partly ascribed to anesthesia and has been suggested to compromise patients' resistance to infection and tumor metastasis. We compared the effects of various anesthetics on natural killer (NK) cell activity and on resistance to experimental metastasis, and studied mediating mechanisms and prophylactic measures. Fischer 344 rats served as controls or were anesthetized for 1 h with ketamine, thiopental, halothane, or propofol. Anesthetized rats were either maintained in normothermia or left to spontaneously reach 33 degrees C-35 degrees C. Rats were then injected IV with MADB106 tumor cells, and 24 h later lung tumor retention was assessed, or 3 wk later, lung metastases were counted. Additionally, the number and activity of circulating NK cells were assessed after anesthesia. All anesthetics, except propofol, significantly reduced NK activity and increased MADB106 lung tumor retention or lung metastases. Hypothermia had no significant effects. Ketamine increased metastasis most potently, and this effect was markedly reduced in rats pretreated with a beta-adrenergic antagonist (nadolol) or with chronic small doses of an immunostimulator (polyriboinosinic:polyribocytidylic acid). Overall, the marked variation in the NK-suppressive effects of anesthetics seems to underlie their differential promotion of MADB106 metastasis. Prophylactic measures may include perioperative immunostimulation and the use of beta-blockers. This study in a rat model of pulmonary metastasis demonstrates that some anesthetics, but not others, increase susceptibility to tumor metastasis, apparently by suppressing natural killer cell activity. Ketamine was most deleterious, and its effects were prevented by peripheral blockade of beta-adrenoceptors combined with low levels of immunostimulation.

Clinical significance of circulating tumor cells, including cancer stem-like cells, in peripheral blood for recurrence and prognosis in patients with Dukes' stage B and C colorectal cancer.

Masaki Mori, Naoko Kato-Hayashi, Mitsuru Sasako … (2011)

Using multiple genetic markers, including cancer stem-like cells, we evaluated the clinical significance of circulating tumor cells (CTCs) as a prognostic factor for overall survival (OS) and disease-free survival (DFS) in the peripheral blood (PB) of patients with colorectal cancer (CRC) who had undergone curative surgery. In a multi-institutional study, 735 patients with CRC were assigned to a retrospective training set (n = 420) or prospective validation set (n = 315). CTCs that expressed carcinoembryonic antigen (CEA), cytokeratin (CK) 19, CK20, and/or CD133 (CEA/CK/CD133) mRNA in PB were detected using real-time reverse transcription polymerase chain reaction assay. In the training sets, OS and DFS of patients who were positive for CEA/CK/CD133 were significantly worse than those of patients who were negative for these markers (P < .001). At each staging analysis, OS and DFS of patients with Dukes' stage B or C cancer who were positive for CEA/CK/CD133 were significantly worse than those of patients who were negative for these markers (P < .003 and P < .001 in Dukes' stage B; P < .001 in Dukes' stage C). In contrast, in patients with Dukes' stage A, no significant differences were seen between patients who were positive for these markers and those who were negative. Cox multivariate analysis demonstrated that CEA/CK/CD133 was a significant prognostic factor for OS (hazard ratio [HR], 3.84; 95% CI, 2.41 to 6.22; P < .001) and DFS (HR, 3.02; 95% CI, 1.83 to 5.00; P < .001). In particular, in patients with Dukes' stage B and C cancer, CEA/CK/CD133 demonstrated significant prognostic value. In validation sets, similar results were confirmed in patients with Dukes' stage B and C cancer. In patients with Dukes' stage B and C CRC who require adjuvant chemotherapy, detection of CEA/CK/CD133 mRNA in PB is a useful tool for determining which patients are at high risk for recurrence and poor prognosis.
