Oxaliplatin is a key chemotherapy drug in patients with colorectal cancer. Administration of oxaliplatin via a peripheral vein often causes vascular pain. However, no studies have evaluated vascular pain in patients with colorectal cancer in relation to peripheral venous administration of chemotherapy with or without oxaliplatin. We evaluated oxaliplatin-induced vascular pain using subjective and objective methods. We determined if oxaliplatin induced vascular pain in patients with colorectal cancer using a Visual Analog Scale (VAS) and a PainVision PS-2100 device. We compared VAS score between chemotherapy regimens with or without oxaliplatin, and between genders. We also examined the correlations of VAS score with pain intensity examined by the PainVision PS-2100, and with age and vessel diameter. A total of 98 patients with colorectal cancer were enrolled in this study, including 78 patients who received oxaliplatin via peripheral venous administration and 20 who received chemotherapy without oxaliplatin. The median VAS scores in patients with and without oxaliplatin were 36.5 (interquartile range 9.0–60.0) and 0 (0–4.0), respectively (P < 0.001), and the median pain intensities according to PainVision were 43.5 (14.3–98) and 36.5 (9.3–58.5), respectively (P < 0.001). There was a positive correlation between VAS and pain intensity (r = 0.584), but no correlation between VAS score and age (r = −0.174) or vessel diameter (r = −0.107). Peripheral venous administration of oxaliplatin induced vascular pain, measured both subjectively and objectively, in patients with colorectal cancer, regardless of vessel diameter.

“…Additionally, it was reported that warming the blood vessels might reduce oxaliplatin-induced venous pain. 19 Therefore, it was proposed that the application of a hot pack would result in the dilation of blood vessels, which may be useful to reduce symptoms of vascular pain after intravenous gemcitabine administration. Indeed, as shown in Figure 1B, our results indicated that the incidence of vascular pain in patients with hot pack use was significantly lower than that in patients without hot pack use, with dosages >930 mg/m 2 .…”

“…These approaches include accessing the large vein in the crease of the forearm for peripheral venipuncture, reducing the speed of administration, increasing the volume of dilution, 14,15 addition of dexamethasone into the solution for pH adjustment, 16,17 administration through a Y-site of the main infusion route of a hydration bag, 18 and warming the vein with a hot pack. 19 However, the efficacy of these methods for preventing vascular pain caused by administration of anticancer drugs, including gemcitabine, has not been fully elucidated.…”
Background: Peripheral intravenous injection of gemcitabine often causes vascular pain; however, preventive measures have not yet been established. Objectives: This study focused on identifying predictive factors for gemcitabine-induced vascular pain. Methods: We retrospectively analyzed risk factors for developing vascular pain in patients with pancreatic cancer receiving gemcitabine infusions at our institution. Infusions were divided into groups according to presence or absence of vascular pain symptoms, and variables were compared. Odds ratios for risk factors were calculated using logistic regression analyses. Results: Overall, 272 patients with pancreatic cancer were subjected to 725 gemcitabine infusions, and of these, 18.4% (n = 50) experienced vascular pain. There were significant differences in the gemcitabine dose ( P = 0.025), dose of gemcitabine/body surface area (BSA; P = 0.004), concentration of gemcitabine ( P = 0.025), and hot pack use ( P = 0.011) between the vascular pain and no vascular pain groups. Multivariable analyses indicated that gemcitabine dose/BSA and lack of hot pack use were risk factors for developing vascular pain. Moreover, on administration of a higher dosage (>930 mg/m2), the incidence of vascular pain in patients using a hot pack (6.7%) was significantly lower than that in patients not provided a hot pack (16.2%). Conclusions and Relevance: High gemcitabine dosages and lack of hot pack use were predictive factors for gemcitabine-induced vascular pain in patients with pancreatic cancer. Patients receiving gemcitabine treatment should apply a hot pack to the injection site. Scrupulous clinical attention is required for patients presenting with these risk factors to improve pain management.
“…We believe that the graphene @VER-M or nano Fe 3 O 4 @VER-M system would be useful for mild PTT in the future. Or more succinctly, other kinds of heat treatments for cancer therapy such as hot compress 80 and hyperthermic perfusion 81 could be enhanced by forming hot compress@VER-M or hyperthermic perfusion@VER-M system.…”
Enhancing the heat-sensitivity of tumor cells provides an alternative solution to maintaining the therapeutic outcome of photothermal therapy (PTT). In this study, we constructed a therapeutic system, which was composed of methoxy-polyethylene-glycol-coated-gold-nanorods (MPEG-AuNR) and VER-155008-micelles, to evaluate the effect of VER-155008 on the sensitivity of tumor cells to heat, and further investigate the therapeutic outcome of MPEG-AuNR mediated PTT combined with VER-155008- micelles. VER-155008- micelles down-regulate the expression of heat shock proteins and attenuate the heat-resistance of tumor cell. The survival of HCT116 cells treated with VER-155008- micelles under 45 °C is equal to that treated with high temperature hyperthermia (55 °C) in vitro. Furthermore, we proved either the MPEG-AuNR or VER-155008- micelles can be accumulate in the tumor site by photoacoustic imaging and fluorescent imaging. In vivo anti-cancer evaluation showed that tumor size remarkably decreased (smaller than 100 mm3 or vanished) when treated with combing 45 °C mild PTT system, which contrasted to the tumor size when treated with individual 45 °C mild PTT (around 500 nm3) or normal saline as control (larger than 2000 nm3). These results proved that the VER-155008- micelles can attenuate the heat-resistance of tumor cells and enhance the therapeutic outcome of mild-temperature photothermal therapy.
