AbstractBACKGROUNDNasopharyngeal carcinoma (NPC) is a commonly encountered type of tumor.Fluorouracil (FU) is an effective treatment providing satisfactory oncologicoutcomes in nasopharyngeal carcinoma patients. We describe a unique case ofcolonic perforation in an NPC patient treated with FU. Thus far, only two cases ofintestinal perforation associated with FU treatment have been reported. We hopethat the analysis of the relationship between the adverse effects of FU andphysiological factors will help to reduce the incidence of colonic perforation inpatients with nasopharyngeal carcinoma treated with FU.
CASE SUMMARYA 67-year-old female patient suffered from NPC stage pT3N2M0. She had ahistory of three surgical procedures: Partial enterectomy, partial sigmoidectomy,and sigmoidostomy. After the administration of 2.75 g FU, a bloody stoolappeared and the patient developed abdominal pain. Subsequent examinationindicated colitis and intestinal perforation.
CONCLUSIONFU is a commonly used drug in NPC chemotherapy. The most common adverseeffect of FU is gastrointestinal reaction, and the colonic perforation found here isthought to be caused by gastrointestinal mucosal injury consequential to the FUtreatment. When selecting chemotherapy drugs, their side effects and thephysical condition of patients should be considered, particularly in patients witha history of gastrointestinal surgery.

Core tip: Intestinal perforation associated with fluorouracil treatment is very rare. Thepossible reason of the perforation in the case presented here is that the patient hasundergone intestinal surgeries, her physical condition was poor, and the use offluorouracil has damaged the intestinal mucosa. In general, patients with intestinalperforation require an immediate surgical treatment. However, the use of radiotherapyand chemotherapy in patients after intestinal surgery is challenging.

INTRODUCTIONFluorouracil (FU) is commonly used in nasopharyngeal carcinoma chemotherapy. Arecent article by Fata et al[1] provides a reminder that FU does cause, directly orindirectly, gastrointestinal mucosal damage, and the awareness among oncologists ofthis problem and resulting complications is necessary. The current report presents acase of colonic perforation induced by FU in a patient with a history of three surgicalprocedures: Partial enterectomy, partial sigmoidectomy, and sigmoidostomy. Colonicperforation is a rare complication of FU therapy. So far, only two cases of intestinalperforation associated with FU treatment have been reported[2,3], and the uniquenessof the medical history of the patient presented here further highlights the clinicalrelevance of the current report.
CASE PRESENTATION
Chief complaintsA 67-year-old female patient felt left mandibular lymph node enlargement,accompanied by headache and tinnitus.
History of present illnessThe left neck mass was found in May 2019, and the mass gradually increased, but shedid not show symptoms of nasal congestion or nosebleed.
History of past illnessSeven years ago, she underwent partial enterectomy, partial sigmoidectomy, andsigmoidostomy.
Physical examinationOn admission, the bilateral cervical lymph nodes of the patient were enlarged, and theswollen lymph node under the left jaw was the largest, with a size of 3.2 cm × 2.6 cm.She had no exophthalmos and no difficulty in deglutition or opening the mouth. Notenderness or rebound tenderness was found on abdominal palpation.
Laboratory examinationsBlood analysis (Figure 1) and urine analysis were normal on August 15, 2019. Chest X-ray, electrocardiogram, and arterial blood gas were also normal.
Imaging examinationsIn August 2019, nasopharyngoscopy identified an undifferentiated non-keratinizingcarcinoma. Additionally, magnetic resonance imaging of the nasopharynx, neck, andskull base documented bilateral thickening of the parapharyngeal wall and posteriorparapharyngeal wall, and multiple lymph node metastases present bilaterally in theparapharyngeal space and the neck. These findings were consistent withnasopharyngeal carcinoma.
Further diagnostic work-upSingle-photon emission computed tomography/computed tomography revealedthickened mucous membranes in the bilateral and posterior parietal walls of thenasopharynx, with soft tissue mass shadows.

A: WBC, NEUT, and RBC; B: FB and D-dimer; C: Hb and PLT.
FINAL DIAGNOSISBased on the combination of imaging, clinical, and pathological results, thenasopharyngeal malignant tumor was diagnosed as pT3N2M0.
TREATMENTThe original treatment plan was to administer the TPF chemotherapy regimen(paclitaxel 180 mg + cisplatin 30 mg + FU 5 g). The first intravenous injection of 0.5 gFU was performed on August 16, 2019, and the remaining 4.5 g was divided into twointravenous doses. On August 19, 2019, after injecting the first of the remaining 2.25 gdoses of FU, the patient developed abdominal pain and bloody stool. Of note,cisplatin and paclitaxel were planned to be given to the patient on that day, but theywere not administered. Blood tests were performed, which showed an increase in D-dimer, white blood cells, neutrophils, red blood cells, and hemoglobin and a decreasein fibrinogen and platelets compared with the results obtained on August 15 (Figure1). A computed tomographic scan (Figure 2) of the abdomen showed freeintraperitoneal air. Colonoscopy revealed mucosal ulceration and erosion in thesigmoid colon and descending colon. The patient was immediately taken to theoperating room for an emergent laparotomy. During the procedure, a perforation wasfound in the descending colon, and a large amount of exudate flowed out of theperforation. A partial colectomy was performed. Colitis was diagnosed based onpathologic examination of surgical specimens.

OUTCOME AND FOLLOW-UPAfter the surgery, the patient was treated with antibiotics. She had diffuse abdominaltenderness to deep palpation. On presentation, her blood pressure was 122/83, pulse85/min, temperature 37.1 °C, respiratory rate 18/min, and oxygen saturation 97%.The patient's condition gradually stabilized over a period of 24 d, but due to theintestinal damage, the induction chemotherapy had to be postponed. The patient andher family have expressed their understanding regarding the reason for postponingthe original treatment plan.
DISCUSSIONInduction cisplatin-FU chemotherapy prior to definitive radiation improves freedomfrom distant metastases, disease-free survival, and overall survival in patients withlocoregional stage IV nasopharyngeal carcinoma without increasing treatment-relatedmorbidity [4 ]. In recent years, docetaxel, cisplatin, and FU-based inductionchemotherapy has been widely applied in the treatment of locoregionally advancednasopharyngeal carcinoma[5]. FU can effectively reduce the recurrence of tumors andprolong survival in patients with nasopharyngeal carcinoma, regardless of whetherthe surgery was performed.
However, the toxic and side effects of FU require careful consideration. Themechanism of adverse effects of FU involves a deficiency of the catabolic pathway, inwhich the drug competes with uracil, the naturally occurring pyrimidine, as anenzyme substrate. Dihydropyrimidine dehydrogenase (DPD, EC 1.3.1.2) is the initialand rate-controlling enzyme of the catabolism of endogenous pyrimidine andfluoropyrimidine nucleotides. DPD enzyme is expressed in most tissues, including thetumors, and is highly active in the liver and peripheral lymphocytes. The activity ofDPD is highly variable among individuals. Low levels of DPD activity have beenassociated with an increased risk of toxicity during the FU treatment[6]. The mostcommon adverse reaction triggered by FU is gastrointestinal tract response. Thepatient presented with colonic perforation, acute diffuse peritonitis, and acuteinfection, and these conditions were, to a large extent, associated with the use of FU.Surgical treatment of colonic perforation resulting from the administration of FU iscrucial, and the prognosis depends essentially on the time to diagnosis. It is veryimportant to increase the knowledge about intestinal perforation in order to improvethe diagnostic accuracy[7].
Perforations of the colon are thought to be caused by damage to the gastrointestinalmucosa consequential to the treatment with FU. Gastrointestinal perforation is aknown adverse event of bevacizumab[8-10], but it occurs only rarely during FUtherapy[2,3]. In particular, descending colon perforation is less frequent than gastricand duodenal perforation. Because of the scarcity of reports of descending colonperforation in patients treated with FU, its frequency and mechanism are not

completely understood. It is possible that the patient had an enterostomy, and FUmay be secondary to the inhibition of the methylation reaction catalyzed bythymidylate synthetase (EC 2.1. 1.45), which transfers a methyl group from N, N’-methylene-tetrahydrofolic acid to deoxyuridylic acid, contributing to the breakup ofthe gastrointestinal mucosa, which leads to intestinal perforation. Accordingly, wehave a reason to believe that the colonic perforation presented in this case report wasassociated with the FU treatment.
In conclusion, although induction chemotherapy can improve the overall survival,side effects of drugs and the patient's physical condition should be all considered inselecting the optimal treatment modality, particularly in patients with a history ofgastrointestinal surgery. The possibility of performing colonoscopy beforechemotherapy should be taken into account in these patients.
