Abstract
The exact incidence of cancer-associated venous thromboembolism (CA-VTE) in patients with oral and facial cancer (OFC) is not exactly known, and this risk is empirically considered to be low. However, this suggestion may result in disease underdiagnosis, prolong the initiation of adequate therapy, and consecutively increase CA-VTE-related morbidity and mortality. In addition, there might be specific clinical problems in the treatment of CA-VTE in patients with oral and facial cancer, such as swallowing difficulties, that might limit the possibilities of oral anticoagulation. Finally, there are limited data regarding the optimal treatment of CA-VTE in patients with oral and facial cancer, and this includes data on novel therapeutic strategies, including the use of direct oral anticoagulants. This article reviews current data on the optimal treatment strategy for CA-VTE in patients with OFC.

[PMID: 36428709 PMCID: PMC9688079 DOI: 10.3390/cancers14225616] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2022] [Revised: 11/11/2022] [Accepted: 11/15/2022] [Indexed: 11/17/2022] Open
Abstract
Venous thromboembolism (VTE) disease is the second leading cause of mortality in cancer patients. In the general population, the annual incidence of a thromboembolic event is about 117 cases per 100,000 persons, but cancer increases this risk about fourfold, while in patients receiving chemotherapy and surgical treatment, it is about sevenfold. Oral squamous cell carcinoma (OSCC) is the most common form of oral cancer and represents a multistep process in which environmental factors and genetic alterations are implicated. Thrombotic risk is considered empirically low in OSCC patients, although few data are available. Having limited information available may result in poor awareness of VTE prevention in OSCC, risking jeopardising the oncologic treatment and increasing the morbidity and mortality among these patients. In this paper, the topic of OSCC-associated thrombosis will be discussed.

Abstract
Venous thromboembolism (VTE) is a common complication for cancer patients. VTE-associated risk varies according to the type of tumor disease. Head and neck cancer is a common cancer worldwide, and most tumors are squamous cell carcinomas due to tobacco and alcohol abuse. The risk of VTE associated with head and neck (H&N) cancer is considered empirically low, but despite the high incidence of H&N cancer, few data are available on this cancer; thus, it is difficult to state the risk of VTE. Our review aims to clarify this situation and tries to assess the real VTE risk associated with H&N cancer. We report that most clinical studies have concluded that there is a very low thrombosis risk associated with H&N cancer. Even with the biases that often exist, this clinical review seems to confirm that the risk of VTE was empirically hypothesized. Furthermore, we highlight that H&N cancer has all the biological features of a cancer associated with a high thrombosis risk, including a strong expression of procoagulant proteins, modified thrombosis/fibrinolysis mechanisms, and secretions of procoagulant microparticles and procoagulant cytokines. Thus, this is a paradoxical situation, and some undiscovered mechanisms that could explain this clinical biological ambivalence might exist.

Abstract
OBJECTIVE To observe the correlation between serum level of TXB2, 6-Keto-PGF1alpha and liver metastasis. METHODS The metastatic model was made by injection of W256 carcinosarcoma. Rats were randomly divided into two groups: rats with blood stasis group and control group. Rats in control group were given normal saline via abdominal cavity once a day. Rats in blood stasis group were injected adrenalin in the fourteenth day. Tumor size and liver metastasis were observed. Serum TXB2 and 6-Keto-PGF1alpha were tested by radioimmunoassay. RESULTS Tumor size in rats with blood stasis was significantly smaller than that of the control group (P<0.01). Occurrence of liver metastasis in rats with blood stasis was significantly lower than that of the control group (P<0.01). The values of 6-Keto-PGF1alpha, TXB2, and TXB2/6-Keto-PGF1alpha were higher in the group with blood stasis. CONCLUSION In the status of blood stasis, W256 carcinosarcoma grows slowly, and liver metastasis increases insignificantly, with the elevations of 6-Keto-PGF1alpha, TXB2 and TXB2/6-Keto-PGF1alpha.

Abstract
The arachidonic acid metabolites, or eicosanoids, are a large series of lipid-derived mediators capable of producing a multitude of physiologic effects in the local environment. They play important roles in a variety of signaling pathways in endocrinology, immunology, and oncology. A significant body of work in this area has occurred in squamous cell carcinomas of the head and neck over the past 15 years. This review will attempt to familiarize the head and neck surgical oncologist with the basic biochemical steps in the formation of these compounds, newer developments in the field of eicosanoid biochemistry, and related experimental evidence of the roles of these substances in head and neck cancer.

Abstract
BACKGROUND Whether or not tumor response to chemotherapy-sensitized radiation therapy (CTRT) for head and neck cancer leads to an improved outcome is unknown. METHODS Forty patients who received preoperative cisplatin plus simultaneous radiotherapy for operable stage III and IV head and neck cancer were reviewed retrospectively regarding clinical demographics, staging, and survival status. RESULTS Twenty-one (57%) patients had a histologic complete response (HCR) and 16 (43%) had a partial (PR) (9) or clinical complete (7) response (CCR). Tumor response of N1 versus N2-3 nodal disease showed 6 (75%) HCR and 4 (25%). Five-year disease-free survival overall was 82% for HCR versus 38% for PR/CCR (P <0.05). Disease-specific 5-year survival was 100% for HCR versus 27% for PR/CCR (P <0.002). CONCLUSIONS Histologic complete response to CTRT for head and neck cancer is associated with increased survival and encouraging disease-free status. Response to CTRT is inversely proportional to lymphatic tumor load.

Abstract
We measured the maximum aggregation rate (MAR) of platelets in 770 patients with malignant head and neck tumors, 55 patients with benign tumors of the head and neck, and 164 healthy people as a control group. The results were as follows: 1. the mean MAR value of patients with malignant tumors was significantly higher than the control group mean value; 2. prior to treatment, the mean MAR value increased with advancing tumor stage; 3. both MAR values of relapsed or metastasized patients and of nonsurvivors in stage III and IV increased significantly compared with survivors or patients recovering from malignant tumors. The results of the present study suggest that MAR values of patients with malignant tumors of the head and neck may serve as indicators in evaluating therapeutic procedures and prognosis.

Abstract
Accepted mechanisms of coagulation are being challenged as new proteins and feedback mechanisms are discovered and evaluated. These new proteins, including tissue factor pathway inhibitor, not only change the way we look at the coagulation mechanism, but also give us potential alternatives in treatment of hemophilia. Gene therapy continues to be a challenging research area, with hemophilia serving as the prototypic hereditary disease target. As acquired disorders of coagulation secondary to immune-mediated events are studied and better understood, our approaches to management of these cases will also change to the benefit of our patients.

Abstract
Head and neck tumors are known to synthesize arachidonic acid metabolites. The authors have postulated that these substances may confer growth advantage to cancer cells, and by interfering with arachidonic acid metabolism squamous cancer growth may be altered. The tongue derived squamous carcinoma cell line, SCC-25, was treated with three leukotriene synthesis inhibitors and indomethacin. A dose-dependent decrease in DNA synthesis occurred with leukotriene inhibition, but not prostaglandin inhibition. All leukotriene synthesis inhibitors produced a dramatic and immediate effect ( > 70% inhibition by 4 hours) without cytotoxicity ( > 90% trypan blue exclusion). Cell populations at 96 hours were decreased when compared to control populations. In conclusion, leukotrienes or other lipoxygenase products may play a role as growth factors for squamous cell carcinoma, and arachidonic acid inhibition may be a novel target for chemotherapeutic intervention.

Abstract
Platelet function in 12 cancer patients was studied sequentially over 97 hr of interleukin-6 (IL-6) daily bolus or continuous infusion (C.I.) therapy. During this period, enhanced ex vivo agonist-induced platelet maximum aggregation (MA) was paralleled by an increase in plasma levels of TXB2 and PF4 as measured by RIA and ELISA, respectively. Platelet-rich plasma (PRP) specimens from bolus IL-6-treated patients demonstrated an increased incorporation of actin-binding protein and myosin in the cytoskeletal core (triton insoluble residue) as shown by sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) in comparison to control specimens. Similarly, the integrin glycoprotein IIIa (GPIIIa) was also observed to be retained into the cytoskeleton by immunoblot. A significant decrease in hypotonic shock response (HSR) was observed over 87 hr of treatment in IL-6 C.I. patients, whereas in IL-6 bolus patients, a significant increase in HSR occurred immediately after the bolus, which was followed by a significant decrease in HSR after 23 hr. These results suggest that IL-6 alters platelet function in vivo.

Abstract
Platelet function in 16 patients with metastatic renal cell carcinoma and melanoma was studied sequentially over the first 96 hr of treatment with moderate and high-dose interleukin-2 (IL-2). During the first 96 hr of therapy, an increased ex vivo platelet maximal aggregation (MA) response to ADP, epinephrine, and arachidonic acid was paralleled by a decrease in the peripheral platelet count. Plasma specimens from patients receiving the moderate dose schedule showed a significant IL-2 induced secretory response of the platelet alpha-granule components beta-thromboglobulin (BTG) and platelet factor 4 (PF4) and the eicosanoid thromboxane B2 (TBX2) as measured by RIA. The increase in TXB2 was highly correlated with MA when analyzed by bivariate regression analysis, whereas the addition of PF4 to TXB2 in a multiple regression analysis further increased their correlation to MA. The observed decrease in peripheral platelet count correlated significantly with MA and PF4 secretion. High-dose IL-2-treated patients showed a statistically significant increase in the percentage of large platelets exceeding 12 fl in diameter and platelet responsiveness to hypotonic shock. These observations suggest that IL-2 therapy results in a reduced peripheral platelet pool, with an increased proportion of the remaining pool of platelets larger, more viable, and activated.

Abstract
Prostaglandins and other eicosanoids have been studied extensively in their physical, biochemical, biophysical and pharmacological aspects. However, studies on their role in tumor progression, especially metastases are relatively recent. Following a brief overview of the history of discovery and metabolism of eicosanoids and other fatty acids, we discuss the functions of these fatty acids (with emphasis on prostacyclin, thromboxane A2, 12-hydroxyeicosatetraenoic acid and 13-hydroxyoctadecadienoic acid) in cell transformation, tumor promotion and particularly in tumor cell metastasis. The relation between these monohydroxy fatty acids and tumor cell metastasis is discussed from three different perspectives, i.e., their effects on tumor cells, on platelets and on endothelial cells. The mechanism of these effects are then addressed at cell adhesion molecule, motility, protease, cell cytoskeleton, protein kinase and eicosanoid receptor levels. Finally, regulation of three key enzymes which generate eicosanoids (phospholipase, prostaglandin endoperoxide synthase and lipoxygenase) is explored.

Abstract
Plasma prostaglandin E (PGE) levels were determined by radioimmunoassay in 53 patients with various stages (II, III, and IV) of hypopharyngeal and laryngeal squamous cell carcinoma, in 12 non-cancer patients and in 10 healthy volunteers. The mean PGE concentration was somewhat higher in non-cancer patients (mean +/- SD = 34.6 +/- 5.37 pg/ml) than in healthy subjects (28.1 +/- 4.96 pg/ml). In spite of a high data variability, the mean preoperative PGE levels in cancer patients were proportional to the stage of the disease and higher than in non-cancer patients (41.2 +/- 19.7 pg/ml, 52.8 +/- 26.7 pg/ml and 82.0 +/- 34.9 pg/ml in stages II, III and IV respectively). The mean plasma PGE concentration significantly decreased for all tumour stages 15-30 days after surgical removal of the tumour, but rose again in some patients within 6-18 months after surgery. The incidence of tumour recurrences 6 and 18 months after surgery was significantly higher in patients with an increased preoperative PGE level (greater than 43.3 pg/ml) than in those patients with a PGE level within the normal range (less than 43.3 pg/ml). The mortality was also higher in the former group, but the difference did not reach the level of significance. Similarly, the mean preoperative and most postoperative concentrations of PGE were significantly higher in patients in whom tumour recurred within 18 months than in tumour-free patients.

Abstract
The production of prostaglandin E ex vivo was studied in samples of 31 squamous cell carcinomas of the head and neck (SCCHN) and 12 adenocarcinomas of gastrointestinal tract (ACGI). As a control, the PGE production was measured in 22 samples of noninvolved mucosa in patients with SCCHN and 12 samples of gastrointestinal mucosas. The mean PGE production by SCCHN was significantly higher than in normal mucosa. Furthermore, the PGE production by tumors which recurred or spread to regional lymph node within 18 months after surgery was higher than in tumors which did not recur within that interval. Also, production of PGE by noninvolved mucosa was significantly higher in patients in which tumor recurred after surgery than in patients which were tumor free. On the other hand, the mean production of PGE by ACGI was not different from that of normal mucosa. These data show that determination of PGE production might have prognostic significance in SCCHN.
